LONDON -- Police made around 150 arrests on Saturday at a protest in central London in support of advocacy network Palestine Action, London's Metropolitan Police said on social media.

Police added that the offenses included "assault on a police officer" and "expressing support for a proscribed organisation."

According to Defend Our Juries, the campaign group organizing the protest, nearly 1,500 people gathered to hold signs reading "I oppose genocide, I support Palestine Action" at Parliament Square near the Westminster Abbey.

On Aug 9, a total of 532 people were arrested for another pro-Palestine Action protest.

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.
