Police in London arrested 466 people on Saturday, August 9, for supporting Palestine Action at the latest and largest protest backing the group since the government banned it last month under anti-terror laws.

The Metropolitan Police said it had made the arrests, thought to be one of the highest number ever at a single protest in the UK capital, for "supporting a proscribed organization." It also arrested eight people for other offenses including five for alleged assaults on officers, though none were seriously injured, it added.
