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.

London's Metropolitan Police arrested more than 466 people at a protest on Saturday against Britain's decision to ban the group Palestine Action, the force said. British lawmakers banned Palestine Action under anti-terrorism legislation in July after some of its members broke into a Royal Air Force base and damaged planes as part of a series of protests.
