Pro-Palestinian activists and supporters stage a protest backing the proscribed group Palestine Action outside the US Embassy in London. (AFP pic)LONDON: British police said Sunday they had arrested 325 people at a London protest in support of Palestine Action the previous day, ahead of a court appeal over the government's contentious ban of the group.

Demonstrators staged a "mass action" outside the US embassy ahead of the Supreme Court holding a two-day hearing from Wednesday on the UK government's July 2025 decision to outlaw Palestine Action under anti-terror legislation.

The US also designated Palestine Action as "terrorist" in August, as the administration of president Donald Trump intensifies its campaign against left-wing movements.
