London police arrest 139 at protest against Palestine Action ban

London police arrested 139 people after hundreds protested the UK government's proscription of Palestine Action as a terrorist organisation, with the majority detained for expressing support for the banned group. Demonstrations also occurred in Edinburgh ahead of a Supreme Court appeal on the ban.

Why it matters. The mass arrests highlight escalating tensions over the UK's ban on Palestine Action, which critics say silences pro-Palestine activism and could set precedents for freedom of expression under counter-terror laws.
