Greta Thunberg was detained by Israeli authorities in 2025 after joining a pro-Palestinian aid flotilla that tried to sail toward Gaza, and was later deported along with other activists.

What actually happened

  • In midā€‘2025, Thunberg joined a multiā€‘boat ā€œGaza flotillaā€ that aimed to challenge Israelā€™s naval blockade of Gaza by delivering humanitarian aid.
  • Israeli forces intercepted the flotilla at sea, brought the vessels to an Israeli port, and detained hundreds of people on board, including Thunberg.
  • Within days, Israel announced that Thunberg and more than 170 other activists were being deported to countries such as Greece and Slovakia, and she was later seen arriving at Athens airport and greeted by supporters.

Claims about her treatment

  • Thunberg and fellow activists described harsh conditions in detention, including poor cell conditions, limited food and water, and generally degrading treatment, which she and others have characterized as abuse or ā€œtorture.ā€
  • Some detainees said Israeli guards forced her to pose holding flags for photos and dragged or manhandled her during the arrest and transfer process.
  • Israel has firmly rejected the mistreatment and torture allegations, saying detainees were given access to food, water, toilets, medical care, and legal counsel, and that all procedures were carried out in accordance with the law.

ā€œKidnappingā€ and political controversy

  • After her release, Thunberg publicly claimed she had effectively been ā€œkidnappedā€ off the aid ship and taken against her will, framing it as part of Israelā€™s attempt to silence solidarity with Gaza.
  • Israeli officials and proā€‘Israel commentators strongly disputed this, arguing she was lawfully detained for attempting to breach a legally enforced blockade, and portraying her as spreading false or exaggerated accusations.
  • The episode fed into a broader political battle: critics accused Thunberg of shifting from climate activism to antiā€‘Israel activism, while supporters framed her actions as consistent with humanā€‘rightsā€‘driven activism and solidarity with Palestinians.

Where things stand now

  • By early 2026, Thunberg is no longer in Israel; she was deported and has continued speaking publicly about Gaza, Israelā€™s blockade, and her experience in detention.
  • Israeli authorities maintain that the naval blockade and interception of flotillas are security measures, while international bodies and many activists argue that the blockade harms civilians and that flotilla crackdowns violate humanitarian principles.
