Greta Thunberg was arrested in London under the Terrorism Act while protesting outside Aspen Insurance over its ties to Elbit Systems, a major Israeli defense contractor.
Greta Thunberg, known for climate activism and recent pro-Palestinian actions, was taken into custody today during a demonstration outside the offices of Aspen Insurance in central London. The protest targeted the firm because it insures Elbit Systems, which drew the demonstrators’ focus. The arrest was carried out under the Terrorism Act, according to reporting on the incident.
Elbit Systems describes itself as “a leading global defense technology company, delivering advanced solutions for a secure and safer world.” The company employs about 20,000 people worldwide and reported $1.92 billion in revenue, with an order backlog of $22.6 billion. Protesters framed their action around Elbit’s role in supplying Israeli defense equipment and the insurance relationships that support it.
Video from the scene shows Thunberg sitting cross-legged on the pavement with a placard when police move toward her. An officer takes her sign and tells her, “You’re going to stand.” After she refuses and shakes her head, the officer asks, “You’re not going to stand up?” and gestures while another person photographs the placard.
Authorities say the arrest followed a broader set of actions by activists tied to Palestine Action, a group proscribed by the U.K. government. According to Reuters, Thunberg was arrested under the Terrorism Act because the British government classifies Palestine Action as a terrorist organization. Two other people were also detained at the scene for throwing red paint on a building during the protests.
A police statement detailed another arrest at the scene and made precise legal claims about the basis for detention: “A little while later, a 22-year-old woman also attended the scene. She has been arrested for displaying an item (in this case a placard) in support of a proscribed terrorist organization (in this case Palestine Action) contrary to Section 13 of the Terrorism Act 2000.” The force characterized its actions as enforcement of proscription laws rather than a simple public order response. That framing has inflamed critics who see heavy-handed treatment of political speech.
Reports also said Thunberg had been among a group that blocked Piccadilly Circus overnight as part of continued demonstrations. The gatherings combined civil disobedience with targeted actions at companies tied to military suppliers. Those escalations are one reason the government moved to treat related activity under the terrorism proscription.
Several members of Palestine Action have been held for more than a year on charges tied to break-ins and alleged damage at defense sites, and families report hunger strikes among detainees. According to reporting, four were jailed over a break-in at an Israeli defense firm last year and four others allegedly breached a military airbase and damaged two aircraft. One family member explained the urgency, saying, “We call on the government…to meet with us urgently because the lives of the hunger strikers are in their hands.”
The U.K. placed Palestine Action on its banned list in July, equating it with extremist groups and making membership a criminal offense carrying up to 14 years in prison. Officials noted that of 1,886 terrorism-related arrests this year, 1,630 were linked to support for Palestine Action. That spike is central to the government’s justification for robust enforcement against people who back or publicly display support for the group.
Thunberg’s recent activism on the Israel-Hamas conflict has included attempts to enter Gaza, which led to her being detained and deported by Israel on two occasions. She has repeatedly described Israel as an “apartheid state” and called its military campaign against Hamas “genocide.” The language and persistent direct actions have widened the divide between high-profile protest tactics and how authorities choose to respond.
Public reaction has been sharp and partisan, with some commenters celebrating the arrest and others denouncing the move as suppressing dissent. One social media post captured the celebratory tone from critics: “Please keep her in jail until after the New Year, as all courts shut for Christmas!! So we will celebrate Christmas and rest!” The arrest adds another chapter to a controversy that mixes celebrity activism, national security law, and heated debate over how democracies handle political protest.
