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.

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.

The crowd in Parliament Square were waving placards supporting the group that was banned this month under anti-terrorism legislation.
