Evening Brief, Friday 11 September

Houthi forces captured Dhubab and landed fighters on Perim Island, putting the Yemeni side of the Bab el-Mandeb Strait under their control after earlier taking Mocha and the Hanish islands. Yemeni government forces backed by Saudi Arabia withdrew from Perim before the landing, while Saudi aircraft later struck Mocha Airport and regional diplomats opened talks aimed at keeping commercial passage open. Donald Trump declined a Saudi request for direct American strikes, a refusal that left Riyadh carrying more of the immediate military burden.

The market reaction was swift because the geography is unforgiving. Perim sits inside a waterway about 20 kilometres wide, through which roughly 12% of global seaborne trade passes, and oil flows through Bab el-Mandeb have risen sharply as Hormuz traffic thinned during the wider US, Israeli and Iranian conflict. Brent and West Texas Intermediate traded above $100 a barrel, diesel prices in the United States hit record levels, and bond markets priced in more inflation risk.

Traders now treat the Red Sea not as a distant war story but as a moving tax on freight, fuel and food. IG analyst Tony Sycamore warned that the conflict could keep stretching across routes and actors.

A small island rarely moves the world economy by itself; this one matters because ships, insurers and central banks all have to price the same narrow passage.

Anthropic published a 154-page threat report describing five incidents in which users tried to steer Claude models toward dangerous biological research, including gain-of-function work on Chikungunya and workflows for adapting H5N1 to mammal transmission. The company also said state-linked actors and cybercriminals in Iran, Russia, China and Yemen used workarounds such as virtual private networks and foreign phone numbers to seek help with surveillance, influence operations, cyber activity and missile or rocket development.

The disclosures landed as AI insiders turned private dread into public politics. Jacob Coxon resigned from Anthropic after four months, gave up unvested equity and said frontier labs were racing toward systems they could not safely control. Other Anthropic staff publicly backed parts of his warning, while members of Congress floated a human-activated kill switch, a pause on advanced training runs and a special AI committee. OpenAI's Sam Altman separately told employees that the company was open to slowing advanced development and coordinating releases with rivals, even as he admitted competitors might not join.

The politics still pull in opposite directions. Bernie Sanders wants a moratorium on advanced AI and a ban on superintelligence, while Donald Trump dismissed calls to halt progress and cast AI as a strategic race the United States must win. That argument will appeal to hawks, but it leaves a practical gap: labs are now reporting misuse by states before governments have written the rules for what counts as acceptable risk.

The industry's old bargain, move fast and patch later, looks weaker when the patches involve pathogens, missiles and machines that may improve themselves.

The United States marked the 25th anniversary of the September 11 attacks with ceremonies in New York, Arlington and Shanksville. Families read the names at Ground Zero, Donald Trump attended the Pentagon ceremony, and JD Vance joined four former presidents in Lower Manhattan. The commemorations recalled the 2,977 people killed when 19 Al Qaeda hijackers seized four planes and struck the World Trade Center, the Pentagon and a Pennsylvania field after passengers fought back.

The anniversary carried the weight of policy as well as grief. It recalled the security state that followed, from reinforced cockpit doors and the Transportation Security Administration to wars abroad and surveillance at home. New York also staged a drone tribute using 2,977 lights over the harbour, while responders and families tried to keep the day centred on victims rather than the politicians who now crowd its edges.

Hong Kong offered a harsher lesson in how governments manage memory. A court sentenced Chow Hang-tung, Lee Cheuk-yan and Albert Ho to prison terms between five years and seven-plus years for inciting subversion under the National Security Law. Their disbanded Hong Kong Alliance had organised the city's annual Tiananmen candlelight vigil for decades, once drawing about 180,000 people to Victoria Park before authorities banned the gatherings and prosecuted organisers.

These two stories do not equate; one honours a national trauma, the other criminalises a commemoration. Together they show why public memory matters, because states that control mourning also shape what citizens may say about power.

Swiss investigators opened a technical inquiry after a Dutch tour coach carrying 45 adults left the road and overturned between Susch and Zernez in the canton of Graubuenden. Five people died and all 40 other passengers were injured, including three in serious condition, after the bus landed in a construction zone on an Alpine route toward Austria. Emergency teams sent seven helicopters and 13 ambulances to the remote crash site, while Dutch diplomats and the tour operator OAD moved staff to the Engadine valley to support families.

In the Philippines, coast guard teams recovered 30 bodies from the burned hull of the MV June Aster after toxic fumes, heat and rough currents kept rescuers off the vessel for about 30 hours. The confirmed death toll rose to 35, with 43 survivors rescued and 54 people still unaccounted for after explosions in the cargo hold sent flames through the ferry off Palawan. Survivors described panic as passengers jumped into the sea, many without life jackets.

The two accidents differ in cause, terrain and jurisdiction, but both turned survivability into a race against access. Safety systems count most when the road is remote, the hull is burning and the passenger list still does not match the human toll.
