LONDON: British police said they arrested seven people on Sunday at a protest near an air base in eastern England used by US forces, accusing them of supporting the banned group Palestine Action.

Activists had gathered to protest the alleged use of the Royal Air Force Lakenheath base as a departure point for US aircraft involved in the war in the Middle East.

The Lakenheath Alliance for Peace, which organized the protest, said the seven had been arrested wearing clothing with the message: “We oppose genocide, we support Palestine Action.”

Police said the five men and two women had been arrested “on suspicion of supporting a proscribed organization.”

Prime Minister Keir Starmer’s Labour government banned Palestine Action as a terrorist organization last year, making it a criminal offense to belong to or support the group.
