On December 23, 2025, Swedish climate activist Greta Thunberg was arrested in central London during a protest organized in solidarity with imprisoned members of Palestine Action who are on hunger strike. The 22-year-old joined demonstrators outside the offices of Aspen Insurance on Fenchurch Street, a company accused of providing services to Elbit Systems UK, the British subsidiary of an Israeli defense manufacturer. The protest began early in the morning when two activists sprayed red paint on the building and locked themselves to the entrance, resulting in their arrests on suspicion of criminal damage. Thunberg arrived later, sitting peacefully while holding a placard that read: "I support the Palestine Action prisoners. I oppose
genocide."City of London Police confirmed the arrest of a 22-year-old woman for displaying an item in support of a proscribed organization—Palestine Action—under Section 13 of the Terrorism Act 2000. Palestine Action was banned in the UK in July 2025 following failed legal challenges.Thunberg, known globally for her climate strikes starting in 2018, has increasingly voiced support for Palestinian causes. In a prior statement, she said: “It is up to the state to intervene and put an end to this by meeting these reasonable demands that pave the way for the freedom of all those who choose to use their rights trying to stop a genocide, something the British state has failed to do themselves.”The hunger strikers, awaiting trial for alleged actions linked to Palestine Action before its ban, demand immediate bail, lifting of the group's proscription, and an end to communication restrictions. Several have been hospitalized, with some on their 52nd day without food, raising serious health concerns.Campaigners have criticized the use of counter-terrorism laws against peaceful protesters, noting hundreds of similar arrests for pro-Palestine signs in recent months.This incident highlights ongoing tensions around free speech, protest rights, and international solidarity movements in the UK.
