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

Police in London have detained more than 466 people who were protesting the United Kingdom’s decision to ban the Palestine Action Group, marking the “largest ever mass arrest” at a single protest in the British capital, according to campaigners.

More than 200 people were arrested in London Saturday during a major pro-Palestinian protest in the British capital, police confirmed.
