Thousands of Palestinians have been forcibly removed from Gaza, sometimes from bomb shelters, and dragged into detention in Israel where some have been tortured and dozens have died, according to a UN human rights office report on Tuesday, Reuters reports.

Many of those seized in Gaza since the onslaught began on October 7 were taken at checkpoints as they fled Israel’s military offensive or from the schools and hospitals where they were sheltering, said the 23-page report based primarily on interviews with released detainees and other victims and witnesses.

Often, they were blindfolded and shackled before being transported to Israel and placed in “cage-like” military centres and forced to wear nothing but diapers for prolonged periods, it said. The UN report said 53 detainees died in custody.

“The testimonies gathered by my Office and other entities indicate a range of appalling acts, such as waterboarding and the release of dogs on detainees, amongst other acts, in flagrant violation of international human rights law and international humanitarian law,” said United Nations High Commissioner Volker Turk in a statement accompanying the report.
