Over 500 arrested at London rally

The protest was organized to challenge the government's designation of Palestine Action as a terrorist organization, a move currently being contested in the High Court.

Those detained range in age from 18 to 87, highlighting the broad demographic involved in the dissent.

Organizers have accused the UK government of complicity in international crimes and criticized the police response as a suppression of free speech.

The mass arrests have intensified the national debate over civil liberties and the right to protest against foreign policy.
