More than 300 arrests at Palestine Action support protest outside US embassy

In a protest outside the US embassy in London, more than 300 individuals were apprehended by the police, according to recent reports. The demonstration, held on Saturday, saw hundreds of people, many of whom held signs expressing opposition to genocide and support for the banned Palestine Action group.

The Metropolitan Police confirmed that 325 individuals were arrested, with 320 of them for expressing support for a proscribed organization under the Terrorism Act. Over 4,000 people have now been detained in connection with the group, which was proscribed in July 2025. The UK Supreme Court is set to review the proscription of Palestine Action following a co-founder's permission to appeal the decision.

Upon their arrest, some protesters were taken to police vans amidst cheers from others present, some chanting "Free, free Palestine." In certain cases, officers had to assist demonstrators who refused to comply. Retired lawyer Charles Allison, who traveled from Cumbria to participate, expressed concerns about the devaluation of civil liberties and hoped the Supreme Court would consider the proscription unlawful.

Defend Our Juries, a group coordinating protests against the ban, stated that the arrest count surpassed 4,000 since the group's proscription. This figure, combined with 3,630 arrests from the year ending June 2026 and those made on Saturday, brings the total to 4,089. Amnesty International UK has criticized the arrests, calling for the government to drop the proscription of Palestine Action, labeling the actions as unjust and an assault on free speech.
