Police arrested protesters outside the US embassy in London on Saturday for expressing support for Palestine Action, a group proscribed under the UK's Terrorism Act. The demonstration, organized by Defend Our Juries, saw over 100 people gather, holding signs that read: “I oppose genocide, I support Palestine Action.” Commander Adam Slonecki of the Metropolitan Police warned that supporting a proscribed organization is unlawful and that organizers and those providing logistical support could also face arrest. The US government designated Palestine Action a terror group in August 2025, and expressing support for the group became an offense in the UK in June 2025. Another demonstration was scheduled for the US consulate in Edinburgh.
