Activists from Switzerland and Spain, part of an international flotilla that attempted to deliver aid to Gaza last week, have alleged inhumane treatment during their detention by Israeli forces, according to statements released by the groups representing them.

Among nine Swiss members who returned home, some reported experiencing sleep deprivation, lack of food and water, and physical abuse, including being beaten, kicked, and confined in cages.

A spokesperson representing the group said these conditions were inhumane and violated basic human rights.

Spanish activists also claimed mistreatment upon their return, describing being beaten, dragged, blindfolded, and insulted, according to lawyer Rafael Borrego, who spoke to reporters at Madrid’s airport late Sunday.

Israel’s Minister of Justice Yariv Levin said on Monday that 170 flotilla activists have been deported, while of the 309 still in custody, 200 were expected to be expelled within the next 24 hours.

Swedish activists, including climate campaigner Greta Thunberg, alleged that she was shoved and forced to wear an Israeli flag during detention.

Others said they were denied clean food and water, and had medication and personal belongings confiscated.

Israel’s foreign ministry rejected the allegations, calling reports of mistreatment “complete lies.”

A spokesperson said all detainees had access to food, water, restrooms, and legal counsel, and that their legal rights were fully respected.

The flotilla, which aimed to deliver humanitarian aid to the besieged Gaza Strip, has drawn international attention to ongoing tensions and human rights concerns in the region.
