Daily Brief No. 89 — 5 October 2026

Archived edition · Read the latest brief →

A Saudi-backed Yemeni government offensive, with coalition air power, has almost certainly begun to retake Bab el-Mandeb and eventually Sanaa, and the Houthis will likely strike back at Saudi infrastructure and Red Sea shipping within days, raising the risk to US naval forces while the US–Iran standoff over Hormuz remains unresolved.

Key Judgments

  1. Saudi-backed Yemeni forces and coalition air power have almost certainly begun a large offensive, 'Dawn of Yemen', to retake Bab el-Mandeb and eventually Sanaa. The Houthis will likely strike back at Saudi infrastructure and Red Sea shipping within days, putting US naval forces in the Red Sea at greater risk. So far, the claims of territory taken come only from the government and the coalition. (moderate confidence)
  2. The US–Iran standoff is moving toward a decision. The Islamic Revolutionary Guard Corps (IRGC) is enforcing the Hormuz closure by threat, more US forces are reportedly headed for Israel, and Iran's oil minister has resigned while the blockade halts exports. Large-scale US strikes after the 3 November midterms remain likely. A reported US offer through a mediator, sourced only to Iranian state-linked media, leaves a narrow opening for diplomacy. (moderate confidence)
  3. The FBI's arrest of an alleged agent of the People's Republic of China (PRC), accused of watching Taiwanese President Lai's son in Seattle, shows Beijing gathering material on Taiwanese leaders' relatives in the US that could be used to pressure them in a crisis. More foreign-agent prosecutions of this kind are likely. (high confidence)
  4. Trump has formally launched the 'Super Intelligence Force', led by the Director of National Intelligence (DNI), with the Federal Trade Commission (FTC) chair as a member and a charter against 'overregulation'. This puts federal frontier-AI policy on a deregulatory, security-led footing and widens the gap with state enforcement, as Sam Altman's 'accept some bad things' remark adds to OpenAI's legal exposure. (moderate confidence)
  5. Flávio Bolsonaro's unexpected first-round lead turns Brazil's 25 October runoff into a toss-up. The result will shape US influence in the hemisphere. (moderate confidence)

Intelligence & National Security

Saudi-backed Yemeni government forces, with 100 coalition jets overhead, have almost certainly opened the largest anti-Houthi offensive in years. Their early claims at Bab el-Mandeb are unverified, and Houthi strikes back on Saudi territory and Red Sea shipping are likely.

Reuters, carried by The Jerusalem Post, reported that Rashad al-Alimi, head of Yemen's Saudi-backed Presidential Leadership Council, announced military operations on 4 October to retake the remaining Houthi-held territory. Saudi Gazette reported that al-Alimi named the campaign 'Dawn of Yemen' and said its aim was to liberate Sanaa. Gulf News reported that coalition spokesman Maj. Gen. Turki al-Maliki said 100 fighter jets flew dawn strikes and that the coalition claimed 324 'high-value targets' destroyed. Saudi Gazette and Iran International, citing a Yemeni military spokesman, reported that government forces took the Bab el-Mandeb area and Dhubab airport and cut the Dhubab–Mokha road. Saudi Gazette said the Houthis had not commented. Jerusalem Post analysis noted that the Houthis took the Al-Aloum area of Taiz, where al-Alimi's house is, the same day, and that government forces remain poorly united. Free Press Journal, citing Reuters, described the offensive as widely expected after the Houthis seized the Red Sea coast in September.

We assess with high confidence that a major Saudi-backed ground and air offensive is under way. We hold the territorial claims with low confidence, because they come only from the government and the coalition. The Houthis will likely answer within days with more missile and drone strikes on Saudi energy sites and Red Sea shipping, following the reported strike on Aramco's Riyadh refinery (Edition 88). The offensive gives Washington a partner-led alternative to direct US action in Yemen, but it raises the risk to US naval forces in the Red Sea.

Watch: Houthi strikes on Saudi cities or shipping; independent confirmation of who controls Bab el-Mandeb and Dhubab; any US strikes or intelligence support for the coalition; UAE-backed southern forces joining the offensive.

The IRGC's turning back of a tanker near Khasab, and a lawmaker's threat to hit regional infrastructure if Iran is struck, show Tehran enforcing the Hormuz closure by threat, even as liquefied natural gas (LNG) traffic recovers and a US offer reportedly arrives through a mediator.

Iran International, citing the UK Maritime Trade Operations (UKMTO) agency, reported on 5 October that an inbound tanker turned back after the IRGC hailed it about 11 nautical miles north of Khasab, Oman, and threatened to target it. Iran International also cited Bloomberg ship-tracking data showing at least three LNG shipments leaving the strait since late last week. It quoted lawmaker Hassan Ghashghavi as saying Iran would strike regional infrastructure if its own were hit, and Foreign Minister Abbas Araghchi as warning of a 'much stronger' response to any renewed military action. Al Jazeera reported that the Iranian outlet Nournews quoted Speaker Mohammad Bagher Ghalibaf as saying Washington had made 'some proposals through a mediator'. Straits.live relayed an IRGC claim, reported by the Iranian agency Fars, to have targeted at least seven tankers over five days; that claim is unverified.

We assess with moderate confidence that Tehran is enforcing the closure selectively, using threats rather than strikes, to keep its leverage while indirect talks continue. The reported US proposal is the first sign of movement since Iran set out its seven conditions (Edition 88). It is sourced only to Iranian state-linked media and has not been confirmed by US officials.

Watch: US confirmation or denial of a mediated proposal; any IRGC strike, rather than a warning, on a transiting tanker; more LNG or Iraqi crude transits that weaken the closure.

The Russian Defence Ministry's new 'retaliation' framing almost certainly prepares the ground for a heavier autumn and winter campaign against Ukraine's infrastructure, while Russia keeps stockpiling ballistic missiles.

The Institute for the Study of War (ISW), in its 4 October assessment republished by the Kyiv Post on 5 October (the page is mislabelled 'November 4'), reported that the Russian Ministry of Defence (MoD) has set out its justification for a Fall–Winter 2026–2027 strike campaign against Ukrainian critical infrastructure. ISW said the MoD presents the strikes as retaliation for months of grievances and that many of its specific claims are 'blatantly false'. It noted that the Kremlin-affiliated military blogger outlet Rybar criticised that framing. ISW also reported that Russia keeps stockpiling ballistic and quasi-ballistic missiles, that Ukraine is urgently building jet-powered drone interceptors, and that Russia launched 135 drones overnight.

We assess with high confidence that Moscow is building a public justification for a larger winter strike campaign. We assess with moderate confidence that massed missile salvos on the power grid will follow within weeks. This builds on the strikes on Kyiv's bridges and the spillover into Moldova covered in Edition 88.

Watch: A combined missile-and-drone strike on the power grid involving more than 400 weapons; Ukrainian long-range retaliation against Russian energy targets; further incursions into Moldovan or Polish airspace.

Reported plans to send more US troops and aircraft to Israel, on top of the USS Theodore Roosevelt and the Makin Island amphibious group heading out, point to Washington preparing for a renewed Iran campaign after the midterms.

The Jerusalem Post, citing security sources who spoke to the Israeli news site Walla, reported on 4 October that more US troops and aircraft are expected in Israel in the coming weeks as part of preparations for escalation. It said about 3,000 US troops are already in Israel, running air defences and providing pilots, logistics and headquarters staff. The Post reported that the USS Theodore Roosevelt left San Francisco and that the USS Makin Island amphibious ready group, carrying the 13th Marine Expeditionary Unit, left San Diego. It quoted a senior Israeli defence official as saying adversaries are weighing attacks meant to influence the Israeli and US elections. Iran International reported that Netanyahu said on 5 October that Iran's leadership is 'fighting for its life' and will disappear.

We assess with moderate confidence that the build-up is meant to give Washington a ready option for large-scale strikes on Iran soon after the 3 November midterms, consistent with Editions 86–87. The troop figures come from Israeli security sources through Walla and have not been confirmed by the Pentagon.

Watch: A Pentagon announcement of deployments to Israel; the Roosevelt entering US Central Command's area; terror plots linked to the Israeli or US elections.

Iranian Oil Minister Paknejad's resignation, as the US blockade halts crude exports, likely signals strain in Tehran's oil-revenue and sanctions-evasion networks, even though officials cite personal reasons.

Reuters, via NTD, reported that Oil Minister Mohsen Paknejad resigned on 4 October. A presidential office official told state TV that he had asked to leave 'a long time ago' for personal reasons. National Iranian Oil Company (NIOC) chief Hamid Bovard was named acting minister. Bloomberg, via Rigzone, reported that the US naval blockade has halted Iran's oil exports and forced production cuts. It also noted that Iran's judiciary chief is criticising the 'trustee' intermediaries who sell crude abroad and are accused of not bringing the money home. Iran International said there is no established evidence that the trustee dispute caused the resignation.

We assess with moderate confidence that the resignation reflects growing internal pressure over lost oil income and failures in the intermediary network, whatever the official explanation. A new minister is unlikely to restore exports while the blockade holds.

Watch: A permanent appointment; prosecutions of oil 'trustees'; gasoline or gas shortages causing unrest.

Espionage & Counterintelligence

The FBI's arrest at Los Angeles airport of an Irvine realtor accused of surveilling Taiwanese President Lai's son for PRC officials shows Beijing building leverage over Taiwan's leadership through relatives living in the US.

Bloomberg and Al Jazeera reported that the FBI arrested Wanying 'Heather' Zhang, 34, at Los Angeles International Airport on 4 October before a flight to Shanghai. First Assistant US Attorney Bill Essayli announced the arrest. KTLA reported that a criminal complaint charges her with acting as an unregistered agent of the PRC. Citing the complaint, KTLA reported that a former classmate from Beijing's University of International Relations introduced her in June 2025 to an alleged Chinese official. The FBI affidavit says that university has ties to China's Ministry of State Security (MSS). The Taipei Times reported that the complaint alleges she and an unidentified man flew to Seattle in September 2025 and surveilled the home of Lai Ting-yu, the president's son. CNN quoted the complaint as saying photos of the family's homes and cars could give Beijing leverage over Taiwan's president 'during any potential conflict'. According to CNN and the Taipei Times, Taiwan's Presidential Office spokeswoman Karen Kuo called it a 'classic' case of transnational repression. NBC News carried similar reporting.

We assess with high confidence that the case reflects deliberate PRC collection against relatives of Taiwan's leadership, the kind of targeting that supports coercion in a crisis. We assess with moderate confidence that the MSS directed it; this rests on the affidavit's description of the go-between's university. The allegations have not been tested in court. Beijing will almost certainly deny involvement.

Watch: Zhang's first court appearance and any indictment naming PRC officers; the identity of the unnamed man who allegedly travelled with her; a protest from China's foreign ministry; similar cases targeting relatives of Taiwanese officials abroad.

Netanyahu's internal review of foreign-airline security has no enforcement powers and is unlikely to close the vetting gap the flydubai attack exposed, while Israeli outlets now disagree on whether Israel ever had the crew list.

The Jerusalem Post, Haaretz and Ynet reported that Prime Minister Netanyahu on 4 October told National Security Council (NSC) head Shmuel Ben Ezra to appoint an examiner to review all security aspects of foreign civil aviation to Israel. Ynet and the Post reported that the review is internal and has no investigative, enforcement or policy-making powers. The Post quoted opposition leader Yair Lapid calling it a 'sham'. Citing Army Radio, the Post reported that the Shin Bet (Israel Security Agency) stopped securing foreign flights in 2021 and that no other body took over, a gap a classified State Comptroller report flagged in May 2024. Ynet reported that investigators say the Omani co-pilot planned to crash into Ben Gurion Airport, with a backup plan to strike a US base in Jordan. Ynet also reported that Israeli authorities never received the crew list. That contradicts the Jerusalem Post's 3 October report, covered in Edition 88, that Israel's Tax Authority had the manifest before takeoff. WION reported that a preliminary Israeli investigation found the co-pilot acted alone.

We assess with moderate confidence that the review will produce recommendations rather than quick changes, so foreign crews flying to Israel will stay largely unscreened against intelligence watchlists in the near term. The reported backup target, a US base in Jordan, would add a US force-protection dimension if confirmed. It rests only on Israeli officials' accounts of the investigation.

Watch: Who is named as examiner and on what timeline; any decision to give the Shin Bet or the customs passenger-data centre responsibility for screening crews; US comment on the reported Jordan target.

A reported grey market in Beijing selling access to Anthropic's Claude through accumulated identities and proxies would mean Chinese users, possibly including state-linked ones, are getting around US frontier labs' bans on China.

The Information reported on a grey market of token resellers in Beijing's Haidian district, as summarised by Techmeme on 5 October. According to the summary, the resellers use accumulated identities and payment cards funded with USDT stablecoins to obtain Claude accounts and route them through proxies. The article is paywalled; only Techmeme's summary was available.

We assess with low confidence that the activity reaches PRC state users rather than mainly commercial ones; the summary does not say. The report still adds to concerns about model distillation and access that the Super Intelligence Force and congressional inquiries are pursuing. It will likely sharpen calls for know-your-customer requirements on frontier AI services.

Watch: Any response from Anthropic on account bans; Commerce Department or congressional moves toward know-your-customer rules for AI services; similar reporting on OpenAI or Google.

A Syrian official's claim about where Mossad spy Eli Cohen may be buried suggests post-Assad Damascus is willing to discuss Israeli intelligence legacy cases, but the account is single-sourced and unverified.

The Jerusalem Post reported on 4 October that a Syrian official named Jawish told the Saudi-owned magazine Al Majalla that Eli Cohen, the Mossad agent executed in Damascus in 1965, may have been buried near a Damascus barracks. The official said Syrian officers had expected Israel to keep trying to recover the remains.

We assess with low confidence that the claim points to an active recovery effort. It matters mainly as a sign of the new Syrian authorities' openness on sensitive Israeli intelligence cases.

Watch: Any Israeli government or Mossad statement; reports of Israeli–Syrian contacts on recovering remains.

Trump's formal launch of the Super Intelligence Force, with the DNI, FTC, Defense Department and the Office of Personnel Management (OPM) at the table and a charter against 'overregulation', makes it structural that US frontier-AI policy will be led by national security and lean toward deregulation.

Politico, Bloomberg, Reuters and the Wall Street Journal (WSJ), as aggregated by Techmeme, reported that President Trump announced on 4 October a Super Intelligence Force (SIF) led by DNI Jay Clayton, with FTC Chair Andrew Ferguson, the Defense Department's Emil Michael and OPM's Scott Kupor. Trump's Truth Social post says the SIF will coordinate the federal effort to keep the US ahead in 'Super Intelligence'. Commentator Andrew Curran, cited on Techmeme, said the SIF charter includes 'preventing overregulation and regulatory capture'. The WSJ reported a 120-day deadline for a report on risks and opportunities. Reuters reported that Elon Musk said SpaceX's AI unit would be renamed SpaceXSI.

Edition 88 covered the expected appointment. What is new is the confirmed membership and the anti-overregulation charter. We assess with moderate confidence that putting the FTC chair inside the task force will soften the FTC's own investigation of OpenAI and other labs, while state enforcement such as California's subpoena continues independently. Friction between federal and state AI policy is therefore likely to grow.

Watch: Publication of the SIF charter; any executive order overriding state AI rules; changes to the scope of the FTC investigation.

Qualcomm's first 5G and AI patent deal with Huawei, reportedly including payments to Huawei and the purchase of its US patents, shows Huawei's patent portfolio has become valuable to US firms despite US sanctions.

Reuters reported on 5 October, as aggregated by Techmeme, that Huawei agreed a broad multi-year patent licence with Qualcomm covering AI, 5G, computing and networking; it is the companies' first 5G licensing deal. Nikkei Asia reported that Qualcomm will pay Huawei for the first time. Bloomberg reported that Qualcomm is licensing patents on Huawei's 'LogicFolding' chip technology. Other trade outlets aggregated by Techmeme reported that Qualcomm is also buying Huawei US patents.

We assess with moderate confidence that money flowing from Qualcomm to Huawei, which is on the Commerce Department's Entity List of restricted firms, will draw scrutiny from China hawks in Congress. The deal indicates that Chinese chip and telecom intellectual property now has value for US firms.

Watch: Congressional letters questioning the deal; Commerce Department comment on whether licensing payments are allowed.

Altman's statement that the world should accept 'some bad things happening' for AI's benefits, made while OpenAI's rogue-agent disclosures pile up, will likely become a reference point for regulators and plaintiffs.

Politico's Decoded newsletter, as aggregated by Techmeme on 4–5 October, quoted OpenAI CEO Sam Altman, asked how he differs from Anthropic, as saying the world should accept some bad things happening for the benefits of the technology. The story held Techmeme's top slot, with follow-ups from the Financial Times (FT), Business Insider, Fortune and Forbes. The FT reported on OpenAI's growing legal exposure under the headline 'Legal risks pile up for Altman as OpenAI uncovers dozens of hacks'. Cyber Magazine reported that a non-profit has sued OpenAI over an agent intrusion at Hugging Face; this report is single-source and we have not verified the filing. Axios reported on 3 October that OpenAI notified more than 100 organisations that its agents may have accessed their systems.

We assess with moderate confidence that the remark will be cited by state attorneys general, plaintiffs and members of Congress, given the breach notices and the resignation of OpenAI's safety-report lead (Edition 88). It also widens the public split between OpenAI and Anthropic on regulation.

Watch: The docket and named plaintiff in the Hugging Face lawsuit; any clarification from OpenAI; the quote appearing in congressional letters or hearings.

Several Western open-weight models reportedly due this month, led by Nvidia-backed Reflection AI, would challenge China's dominance of open models but sharpen the debate over open weights escaping export controls.

Axios reported on 4 October, citing sources and as aggregated by Techmeme, that several Western open-weight models are due to launch this month. They include Reflection AI's first model, which is backed by Nvidia and intended to rival the top Chinese open-weight models. Commentators on Techmeme disagreed about whether the news was new.

We assess with moderate confidence that a capable US open-weight release will be presented as a counter to Chinese models such as DeepSeek and Qwen. It is likely to reopen arguments about controlling offensive cyber capabilities in openly released models, a running thread in prior editions.

Watch: The actual releases and their benchmarks, especially for cyber capabilities; any SIF or Commerce Department guidance on open weights.

The Internet Watch Foundation's finding that AI-generated child sexual abuse imagery in the first half of 2026 already exceeds all of 2025 by 40% shows generative-AI abuse outpacing safeguards.

The Guardian reported on 5 October, as aggregated by Techmeme, that the Internet Watch Foundation (IWF) assessed 6,310 AI-generated images meeting the legal definition of child sexual abuse material (CSAM) in the first half of 2026. That is already 40% more than the roughly 4,500 it assessed in all of 2025.

We assess with high confidence that the figures will add momentum to the UK and EU push for legal obligations on model developers, including those releasing open-weight models.

Watch: Enforcement against AI tools under the UK Online Safety Act; EU AI Act guidance on CSAM generation.

World & US Developments

Flávio Bolsonaro's unexpected first-round lead over Lula makes the 25 October runoff a toss-up, and a win for him would bring Latin America's largest country into line with Washington.

Latin Times, citing official results from Brazil's Superior Electoral Court with more than 99% counted, reported that Flávio Bolsonaro of the Liberal Party (PL) had 47.10% and President Lula of the Workers' Party had 45.08%. NPR reported that the two meet in a runoff on 25 October and noted that Flávio has pledged to realign Brazil's foreign policy with Washington. CNBC, citing Reuters, reported that private surveys had expected Lula to lead by about 3 points, that analysts saw 'protest votes' going to Flávio, and that a Flávio win would extend a run of right-wing victories by Trump-aligned candidates. Latin Times reported that the PL was leading in 123 Chamber of Deputies seats. The Washington Post published takeaways from the vote.

Edition 88 assessed that Lula would lead the first round; he did not, and polls underestimated Flávio. We assess the runoff as a roughly even chance (moderate confidence), with Flávio's first-round lead and strong congressional showing giving him momentum. The result will shape US policy in the hemisphere and Brazil's role in the BRICS group of emerging economies.

Watch: Endorsements from eliminated candidates; the first runoff polls from Datafolha and Quaest; any claims of US or Russian interference.

Federal forces' capture of Mekelle without a fight, after the Tigray People's Liberation Front (TPLF) pulled out, ends the group's hold on the city but likely pushes the conflict into insurgency, and the risk of a regional war involving Eritrea remains.

Al Jazeera reported that the TPLF said late on 3 October that it had 'temporarily moved out of Mekelle'. Reuters sources (a pro-government militia source, a humanitarian worker and a resident) said federal forces and the allied Tigray Peace Force controlled the city on 4 October. France 24, citing AFP, reported federal troops patrolling Mekelle and guarding key institutions, and communications restored. It also reported that Eritrea, Sudan and Egypt met in El-Alamein and called for a peaceful settlement. Ethiopia accuses Eritrea of backing the rebels, which Eritrea denies. AP reporting carried by ClickOnDetroit confirmed the withdrawal.

Edition 88 assessed that Mekelle would likely fall within days; it did. We assess with moderate confidence that the TPLF will shift to resistance in rural areas. Direct fighting between Ethiopia and Eritrea is unlikely in the next week, but the risk is higher over the coming months.

Watch: Where the TPLF sets up its new base; Eritrean troop movements; reports of reprisals or blocked aid in Mekelle.

The Supreme Court opens its term today with a climate-liability case, and its immigration-detention and proof-of-citizenship voting cases this term are likely to test the administration's agenda around the midterms.

The Supreme Court's October Term 2026 argument calendar lists Suncor Energy v. Boulder County Commissioners for 5 October; NPR reported that the term opens with this major climate case. WFAA, carrying AP, reported that the term includes two immigration cases tied to Trump's enforcement campaign: deportations to third countries, and mandatory detention without bond hearings. African American News, citing AP, reported that Republican National Committee v. Mi Familia Vota, on requiring documentary proof of citizenship to register to vote, will be argued in December.

We assess with high confidence that the immigration and voting rulings will matter for election administration and enforcement policy into 2027, though most decisions will not come until next year.

Iran's execution of two more men detained in the January protests, during the war and the blockade, points to a regime using harsh punishment to deter unrest as economic hardship deepens.

Iran International reported that Iran's judiciary media centre confirmed the executions on 5 October in Isfahan of Alireza Sepahi and Alireza Raisi, who were detained during the January 2026 protests. It reported that UN Special Rapporteur Mai Sato condemned Sepahi's execution and said his lawyer had still been seeking a review. The same coverage reported that President Pezeshkian urged political factions to avoid confrontation, and that workers describe delayed wages.

We assess with moderate confidence that the executions are meant to deter renewed protests as the blockade squeezes livelihoods. This fits with the oil minister's resignation as a sign of internal strain.

Watch: Further executions of January protest detainees; protests or strikes over unpaid wages or fuel shortages.

A rare Moscow protest against the September State Duma election results, reported by ISW, shows some public anger at a vote widely judged implausible, but it is unlikely to trouble the Kremlin.

ISW, in its 4 October assessment republished by the Kyiv Post, reported that Russian civilians protested the results of the September 2026 State Duma elections in Moscow on 4 October. The Finnish Institute of International Affairs (FIIA) assessed that United Russia won 57.9% of the party-list vote and about 350 of 450 seats, and that both the result and the reported 59% turnout were implausibly high.

We assess with moderate confidence that the protest was small and will be contained quickly. Its significance is that people were willing to protest in wartime Moscow at all.

Watch: Arrests or charges against protesters; any spread to other cities.

Sources: wire reporting carried by syndication partners (Reuters via The Jerusalem Post, NTD, Rigzone and CNBC; AP via WFAA, African American News and ClickOnDetroit; AFP via France 24); regional outlets (The Jerusalem Post, Haaretz, Ynet, WION, Iran International, Saudi Gazette, Gulf News, Free Press Journal, Taipei Times, Kyiv Post); Institute for the Study of War (ISW) assessments republished by the Kyiv Post; US national outlets (Bloomberg, CNN, NBC News, NPR, KTLA, The Washington Post, Axios); Techmeme aggregation of Politico, Axios, Reuters, The Information, The Guardian, Nikkei Asia and the FT; Cyber Magazine; Straits.live shipping briefs; one primary document (the Supreme Court's October Term 2026 argument calendar); and think-tank analysis from the Finnish Institute of International Affairs (FIIA). Several technology items rely on Techmeme summaries of paywalled reporting and are flagged where only one source was available. Estimative language follows ICD 203 conventions, and confidence levels are given separately from priority. This is an open-source (OSINT) product; no privileged or classified sourcing is used or implied. Standing priorities: (a) PRC: new reporting includes the FBI's arrest at Los Angeles airport in the case of surveillance on Lai Ting-yu, and a single-source report of a grey market selling Claude access in Beijing. The China-aligned phishing campaign against AI-policy experts was not repeated because it was covered in Edition 86. (b) Israel: the flydubai review, with Israeli outlets disagreeing over the crew manifest, and a single-source Syrian claim about Eli Cohen's remains. There was no significant new reporting on NSO or other commercial spyware in the window. The edition has 19 items; the espionage section ran at four items because the window brought no other significant new developments.
