Swedish climate activist Greta Thunberg was arrested by Israeli forces while aboard a humanitarian aid vessel bound for Gaza. The flotilla, part of the Global Sumud mission, aimed to deliver essential supplies and challenge Israel’s 16-year blockade on Gaza.
In total, 437 campaigners, parliamentarians, and lawyers joined the mission across more than 40 vessels. However, between Thursday and Friday, Israeli forces intercepted all boats and detained every crew member. Most of the detainees are now held at Ketziot Prison—also known as Ansar III—a high-security facility in the Negev desert that usually holds Palestinian prisoners accused of militant activities.
Thunberg Describes Poor Prison Conditions
After her arrest, Thunberg told Swedish officials that she faced harsh treatment and inhumane conditions. In an email obtained by the Swedish Foreign Ministry, an official who visited her reported that she was deprived of enough food and water and kept in a cell infested with bedbugs.
“The embassy has been able to meet with Greta,” the email stated. The email also read “She informed of dehydration. She has received insufficient amounts of both water and food."
The email also read, "She had developed rashes, which she suspects were caused by bedbugs. She spoke of harsh treatment and said she had been sitting for long periods on hard surfaces.”
Furthermore, other detainees claimed that Israeli forces took photos of Thunberg and forced her to hold flags, though the type of flags remains unknown. A Swedish official added that Thunberg “wondered whether images of her had been distributed.”
Witnesses Confirm Allegations of Physical Abuse
Moreover, two released members of the flotilla supported Thunberg’s claims. Turkish activist Ersin Çelik said, “They dragged little Greta [Thunberg] by her hair before our eyes, beat her, and forced her to kiss the Israeli flag. They did everything imaginable to her, as a warning to others.”
Additionally, journalist Lorenzo D’Agostino, another flotilla participant, said after returning to Istanbul that Thunberg was “wrapped in the Israeli flag and paraded like a trophy.” Witnesses described the scene with disbelief and anger, calling it an act meant to humiliate the activist.
Mission Blocked Before Reaching Gaza
The Global Sumud flotilla’s goal was to deliver humanitarian aid to Gaza despite Israel’s maritime blockade. However, the Israeli military stopped the mission before it reached its destination. Consequently, all vessels were seized, and their crews were detained.
In previous similar cases, activists—including Thunberg—were detained but not criminally prosecuted. Their presence in Israeli-controlled waters was often treated as an immigration issue instead of a criminal offense.
Sweden and Rights Groups Demand Accountability
Meanwhile, Sweden’s Foreign Ministry said it continues to monitor Thunberg’s situation closely. Swedish diplomats have raised concerns about her treatment and have called for her immediate release and transparent investigation into the allegations.
Human rights groups have also condemned the reported abuse, urging Israel to respect international law and ensure the safety of detained activists. The case has now sparked widespread outrage across Europe, with supporters demanding justice for Thunberg and others arrested during the flotilla mission.
