How Hamas Weaponized Sexual Violence on Oct. 7

Maybe 40 yards in front of him, he recalled, a white van pulled up and its doors flew open.

He said he then saw five men, wearing civilian clothes, all carrying knives and one carrying a hammer, dragging a woman across the ground. She was young, naked and screaming.

“They all gather around her,” Mr. Cohen said. “She’s standing up. They start raping her. I saw the men standing in a half circle around her. One penetrates her. She screams. I still remember her voice, screams without words.”

“Then one of them raises a knife,” he said, “and they just slaughtered her.”

Shoam Gueta, one of Mr. Cohen’s friends and a fashion designer, said the two were hiding together in the streambed. He said he saw at least four men step out of the van and attack the woman, who ended up “between their legs.” He said that they were “talking, giggling and shouting,” and that one of them stabbed her with a knife repeatedly, “literally butchering her.”

Hours later, the first wave of volunteer emergency medical technicians arrived at the rave site. In interviews, four of them said that they discovered bodies of dead women with their legs spread and underwear missing — some with their hands tied by rope and zipties — in the party area, along the road, in the parking area and in the open fields around the rave site.

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.”

Similar discoveries were made in two kibbutzim, Be’eri and Kfar Aza. Eight volunteer medics and two Israeli soldiers told The Times that in at least six different houses, they had come across a total of at least 24 bodies of women and girls naked or half naked, some mutilated, others tied up, and often alone.

A paramedic in an Israeli commando unit said that he had found the bodies of two teenage girls in a room in Be’eri.

One was lying on her side, he said, boxer shorts ripped, bruises by her groin. The other was sprawled on the floor face down, he said, pajama pants pulled to her knees, bottom exposed, semen smeared on her back.

Because his job was to look for survivors, he said, he kept moving and did not document the scene. Neighbors of the two girls killed — who were sisters, 13 and 16 — said their bodies had been found alone, separated from the rest of their family.

The Israeli military allowed the paramedic to speak with reporters on the condition that he not be identified because he serves in an elite unit.

Many of the dead were brought to the Shura military base, in central Israel, for identification. Here, too, witnesses said they saw signs of sexual violence.

Shari Mendes, an architect called up as a reserve soldier to help prepare the bodies of female soldiers for burial, said she had seen four with signs of sexual violence, including some with “a lot of blood in their pelvic areas.”
