More than 300 arrested outside US embassy after supporting Palestine Action

More than 300 demonstrators have been arrested after they gathered outside the US embassy in London in support of proscribed group Palestine Action.

Hundreds of people took part in the protest in Nine Elms, south-west London, on Saturday, with many holding signs reading: “I oppose genocide, I support Palestine Action.”

In a post on X on Sunday, the Metropolitan Police said it had arrested 325 people, with the majority (320) detained for expressing support for a proscribed organisation under the Terrorism Act.

Expressing support for the group is an offence under the Terrorism Act after it was proscribed in June 2025.

Many demonstrators applauded and chanted “free, free Palestine” as people were arrested and taken to police vans parked on Ponton Road, just off the embassy grounds, before being transferred to police stations on Saturday.
