British government will use antiterrorism laws to ban campaign organisation in the wake of damage to planes by activists.

The British government has said it will deploy antiterrorism laws to ban Palestine Action, a prominent campaign organisation that has protested against Israel’s genocidal war in Gaza and the United Kingdom’s role in supporting it, in the wake of its activists damaging two military planes.

Protesters clashed with police in London’s Trafalgar Square on Monday at a demonstration in solidarity with Palestine Action. The crowd moved towards police when officers tried to detain someone, while protesters chanted “let them go”.

The government’s move will make it a criminal offence to belong to the pro-Palestinian group and effectively place them in the same category as Hamas, Hezbollah, al-Qaeda or ISIL (ISIS) under British law.

It would be illegal for anyone to promote Palestine Action or be a member. Those who breach the ban could face up to 14 years in prison.
