London Police Arrest 325 at Protest Backing Palestine Action Days Before a UK Supreme Court Hearing on the Ban

British police said Sunday they arrested 325 people at a London protest in support of Palestine Action the day before, according to an AFP report carried by Breitbart London.

The protest. Demonstrators held a "mass action" outside the U.S. embassy ahead of a two-day UK Supreme Court hearing, starting Wednesday, on the government's July 2025 decision to outlaw the group under anti-terror law. The Metropolitan Police said, "In total, 325 people were arrested yesterday," and that "the vast majority of arrests, 320, were for expressing support for a proscribed organisation under the Terrorism Act."

The law. The ban puts Palestine Action on a list that includes Hamas, and membership or support is a crime punishable by up to 14 years in prison. The report says more than 4,000 people, including many senior citizens and Holocaust survivors, have been arrested for showing support, according to campaigners and police tallies. It adds that the United States designated the group as terrorist in August, as the Trump administration steps up its campaign against left-wing movements.

Scotland. A smaller group rallied outside the U.S. consulate in Edinburgh on Saturday and no arrests were made at the time. Police Scotland said it is working to identify people seen wearing T-shirts and holding banners supporting the group, and that "further action will be taken as appropriate."

What to keep in mind. The headline's "terror group" label is Breitbart's and reflects the British and U.S. designations. Supporters and critics of the ban disagree about whether the law is being applied fairly, and the Supreme Court hearing will address the ban itself. The 4,000 figure comes from campaigners and police tallies as cited in the wire report, and we have not checked it.
