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

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

More than 100 people have been arrested at a demonstration against the terror ban of the group Palestine Action. Hundreds of people have gathered in Parliament Square in Westminster to hold up signs, which read: “I oppose genocide. I support Palestine Action”. 150 people have been arrested at the action so far.
