London police arrested 139 people during a protest outside the US Embassy on October 31, organized by Defend Our Juries against the UK's designation of Palestine Action as a terrorist organization. Most arrests were for supporting a banned group. Organizers claim over 4,000 arrests since July 2025. A Supreme Court hearing on the designation is scheduled for Wednesday.

London's Metropolitan Police arrested 139 people during a demonstration outside the US Embassy on Saturday, October 31, 2026, after protesters expressed support for Palestine Action, a pro-Palestinian group outlawed in the UK and designated a terrorist organization. The police said most of those detained were arrested for expressing support for a banned organization. Many demonstrators were pensioners carrying signs reading, "I oppose genocide, I support Palestine Action." One protester climbed a tree near the embassy. The demonstration was organized by Defend Our Juries, which campaigns against the government's decision to outlaw Palestine Action. Organizers claim more than 4,000 people have been arrested since July 2025 for violating the ban and condemned the arrests as a violation of civil rights. The article notes that Palestine Action activists previously vandalized Elbit Systems facilities and a Royal Air Force base. The US also designated the group a terrorist organization in August. A protest also occurred outside the US Consulate in Edinburgh, with no arrests reported. The demonstrations precede a Supreme Court hearing on Wednesday regarding an appeal against the terrorist designation.
