Police in London arrested dozens of demonstrators on Saturday for showing support for Palestine Action, a pro-Palestinian activist group recently banned by the UK government under terrorism laws. Officers said the arrests were made to prevent public disorder after the group urged people to defy restrictions, Reuters reported.

The government outlawed Palestine Action in July after members broke into a Royal Air Force base and damaged aircraft. The group campaigns against British arms sales to Israel and accuses the UK of complicity in what it calls Israeli war crimes in Gaza. Its supporters dismiss the ban as political repression.
