GENEVA: Nine members of the Gaza aid flotilla arrived home in Switzerland on Sunday after being deported by Israel, with some alleging they had been subject to inhumane conditions whilst in detention there, the group representing them said.

An Israeli foreign ministry spokesperson rejected the allegations. The foreign ministry has previously said that claims of mistreatment against detainees are “complete lies.” Nineteen Swiss nationals, including the former mayor of Geneva Remy Pagani, were aboard boats in the flotilla of dozens of vessels that tried to deliver aid to Israeli-blockaded Gaza.

They were taken into custody on Wednesday by Israeli forces who intercepted the flotilla at sea and taken to Israel’s Ktzi’ot prison, according to the Waves of Freedom flotilla group.

Nine of the group returned to Geneva on Sunday afternoon.

“The participants condemned the inhumane detention conditions and the humiliating and degrading treatment they suffered upon their arrest and incarceration,” a statement by the group said. Israel said on Sunday that the legal rights of the activists were being “fully upheld,” that no physical force was used and all detainees were given access to water, food, and restrooms.
