British police have arrested dozens of people for supporting a banned Palestinian rights organization as protests over the government’s decision to outlaw the group continued for a third weekend.

Separately, a march organised by the Palestine Coalition took place in London on Saturday. The Met said 10 people had been arrested so far at that demonstration, including eight suspected of supporting Palestine Action.

The Keir Starmer-led government recently designated Palestine Action as a terrorist organisation under the Terrorism Act 2000, making any form of support or affiliation with the group a criminal offence.
