Numerous women who were released have testified that they and many of the other women they met in the tunnels had been brutalised, sexually assaulted and raped, as well as verification by doctors.

At least 10 of the Israeli civilians released by Hamas, both men and women, were sexually assaulted or abused while in captivity, the Associated Press reported Wednesday.

In a report detailing allegations of severe and widespread sexual abuse by Hamas terrorists during their October 7 onslaught and later against hostages, a doctor who treated some of the 110 hostages released from captivity told the AP that at least 10 men and women among those freed were sexually assaulted or abused.

Many of the accounts are difficult to bear, and the visual evidence is disturbing to see.

The Times viewed photographs of one woman’s corpse that emergency responders discovered in the rubble of a besieged kibbutz with dozens of nails driven into her thighs and groin.

The Times also viewed a video, provided by the Israeli military, showing two dead Israeli soldiers at a base near Gaza who appeared to have been shot directly in their vaginas.

The first victim she said she saw was a young woman with copper-color hair, blood running down her back, pants pushed down to her knees. One man pulled her by the hair and made her bend over. Another penetrated her, Sapir said, and every time she flinched, he plunged a knife into her back.

She said she then watched another woman “shredded into pieces.” While one terrorist raped her, she said, another pulled out a box cutter and sliced off her breast.

“One continues to rape her, and the other throws her breast to someone else, and they play with it, throw it, and it falls on the road,” Sapir said.

She said the men sliced her face and then the woman fell out of view. Around the same time, she said, she saw three other women raped and terrorists carrying the severed heads of three more women.

Sapir provided photographs of her hiding place and her wounds, and police officials have stood by her testimony and released a video of her, with her face blurred, recounting some of what she saw.

Jamal Waraki, a volunteer medic with the nonprofit ZAKA emergency response team, said he could not get out of his head a young woman in a rawhide vest found between the main stage and the bar.

“Her hands were tied behind her back,” he said. “She was bent over, half naked, her underwear rolled down below her knees.”

Yinon Rivlin, a member of the rave’s production team who lost two brothers in the attacks, said that after hiding from the killers, he emerged from a ditch and made his way to the parking area, east of the party, along Route 232, looking for survivors.

Near the highway, he said, he found the body of a young woman, on her stomach, no pants or underwear, legs spread apart. He said her vagina area appeared to have been sliced open, “as if someone tore her apart.”

Many of the Israeli hostages, according to interviews with family members, returned “malnourished, infested with lice, ill, injured and deeply traumatized,” the Times also reported.

Also important to note, it is likely that some hostages are treated under “acceptable” conditions for propaganda purposes. Also, many hostages’ family members were murdered on october 7. So that unto itself very much contradicts with the absurd claim that they were “treated well”.
