Dozens arrested after UK brands Palestine Action a 'terror group' | 13 July 2025 | More than 70 people were arrested across the UK on Saturday on suspicion of supporting the activist group Palestine Action, which was recently designated a terrorist organization. The Metropolitan Police said 41 people were arrested in London, where protesters gathered in Parliament Square to demonstrate against Israel's war in Gaza. Some held signs reading "I oppose genocide, I support Palestine Action." Arrests were also made in Manchester, Cardiff, and Leeds. It has been illegal to be a member of Palestine Action or to show support for the group since Saturday, when the new designation came into effect.
