The number of South Africans abducted by Israeli forces, as they sailed on an international flotilla to break Israel’s crippling siege on Gaza, has risen to six. Late on Thursday, 2 October 2025, it was confirmed that activist Carrie Shelver from the Eastern Cape and Johannesburg and currently living in Switzerland, was also aboard one of the Flotilla boats and taken into Israeli detention.
Diana Buttu, a Palestinian human rights lawyer, said Israel’s flotilla interception also amounted to a clear violation of international law.
“It’s important to keep in mind that all of these ships were in international waters,” she said.

A number of foreign governments have lashed out at Israel’s detention of the activists and called in Israeli diplomats to express their outrage and demand explanations.

Israel’s security minister, Itamar Ben-Gvir, who has eight convictions for racism and for supporting the terrorist organisation Kach, said that those arrested would be treated as “terrorists”.
Palestinian security prisoners’ conditions under Ben-Gvir’s ministry are on record for harsh and inhumane conditions.
The activists are reportedly being held in Ketziot prison in the Negev.
Israeli rights group Adala warned that the flotilla detainees were being denied due process.
