At least 365 arrested at London protest supporting Palestine Action

At least 365 people were arrested on Saturday at a protest in support of Palestine Action, a group proscribed as a terrorist organization in July, London's Metropolitan Police said on social media.

Police estimated that around 500 to 600 people were in Parliament Square when the protest began. It noted that anyone in the square holding a placard expressing support for Palestine Action was "either arrested or is in the process of being arrested."

Seven arrests were made for other offences, including five for assaults on officers, police added.

In a separate statement, the Metropolitan Police warned about a "National March for the Hostages" in central London on Sunday, organized by Stop the Hate and several Jewish organizations.

In July, Members of Parliament voted to proscribe Palestine Action as a terrorist group after its members broke into Royal Air Force Brize Norton in June, spraying two Voyager aircraft with red paint and causing 7 million pounds (9.38 million U.S. dollars) worth of damage. The group claimed responsibility for the incident at the time.
