Police arrested 466 people in central London on Saturday for protesting the British government’s decision to ban the pro-Palestinian activist group Palestine Action under anti-terrorism laws.

British Parliament in early July passed a law banning Palestine Action and making it a crime to publicly support the organization.

British police said they arrested 365 people in central London as supporters of a recently banned pro-Palestinian group intentionally flouted the law as part of their effort to force the government to reconsider the ban.
