Greta Thunberg arrested supporting Palestinian prisoners on hunger strike during London protest

Climate activist Greta Thunberg was arrested in London on Tuesday while participating in a protest supporting Palestinian prisoners on hunger strike in British prisons. The protest, organized by Prisoners for Palestine, advocated for Palestine Action members who have been banned as terrorists. Thunberg was seen holding a sign expressing support for the prisoners and opposing "genocide," a reference to the conflict in Gaza. She was later released on bail. The protest aimed to raise awareness of the prisoners' situation and express solidarity with the Palestinian cause.

On December 23, 2025, Greta Thunberg and two others were arrested by British police at a pro-Palestinian protest in London's financial district. The protest, organized by Defend Our Juries, took place outside the offices of Aspen Insurance, which insures Israeli arms manufacturer Elbit Systems. Thunberg was arrested for holding a placard supporting Palestine Action prisoners and opposing what she called "genocide," a violation of the Terrorism Act. Two other protesters were arrested for gluing themselves to a nearby building and causing damage with hammers and red paint. The demonstration aimed to highlight Aspen Insurance's alleged complicity in genocide and show solidarity with Palestine Action members, a group proscribed as a terrorist organization by the UK government, some of whom are currently on hunger strike in British prisons.

Greta Thunberg, the Swedish activist, was arrested in London on Tuesday, December 23, 2025, for allegedly supporting the banned group Palestine Action.
