CNN later confirmed the identity of the woman as German-Israeli national Shani Louk.

Her cousin confirmed to the Washington Post that Louk attended the music festival.

CNN does not know Louk’s whereabouts or condition at this time. CNN is not airing the video because it is graphic and disturbing.

“We recognized her by the tattoos, and she has long dreadlocks,” Louk’s cousin told the Washington Post. “We have some kind of hope… Hamas is responsible for her and the others.”

Israeli border communities

Hamas fighters took hostages in the border community Be’eri, and the town of Ofakim, 20 miles east of Gaza, IDF spokesman Brig. Gen. Daniel Hagari said on Saturday, adding that the two locations were the “main focal points” of the unfolding crisis.

In a televised address, he said that there were special forces with senior commanders in the two communities, and fighting was ongoing in 22 locations.

One video, geolocated by CNN to Be’eri, appears to show Hamas militants taking multiple Israelis captive.

Residents in Be’eri and another community on Israel’s border with Gaza, Nir Oz, told the country’s Channel 12 television station that assailants were going door to door, trying to break into their homes.

Channel 12 also reported that infiltrators had taken hostages in Netiv HaAsara. Israeli authorities did not immediately confirm any details about those reports.

One Israeli mother told CNN she had been on the phone with her children, aged 16 and 12, who were home alone when they heard gunshots outside and people trying to enter. Then, over the phone, she heard the door break down.

“I heard terrorists speaking in Arabic to my teenagers. And the youngest saying to them ‘I’m too young to go,’” the mother said. “And the phone went off, the line went off. That was the last time I heard from them.” CNN is not identifying the mother and her children for safety reasons.

Another Israeli father told CNN he suspects his wife and young daughters may have been abducted while visiting Nir Oz. He said he recognized his wife in a viral video that shows a group of people being loaded on the back of a truck flanked by Hamas militants, while chants of “Allahu Akbar” ring out.

“I don’t even know what the situation is regarding the hostages, and the situation is not looking good,” Yoni Asher said, adding that he tracked his wife’s phone and learned that it was located in Gaza.

In another video, geolocated by CNN to Gaza’s Shejaiya neighborhood, a barefoot woman is pulled from the trunk of a Jeep by a gunman and then forced into the backseat of the car. Her face is bleeding, and her wrists appear to be cable-tied behind her back. The jeep also appears to have an IDF license plate, suggesting it may have been stolen and brought into Gaza.

Soldiers

Al Qassam Brigades claimed to capture “dozens” of Israeli soldiers on Saturday.

“We bring good news to our (Palestinian) prisoners and our people that the al Qassam Brigades have dozens of captured (Israeli) officers and soldiers in their hands,” the group’s spokesman Abu Obaida said in a post on Telegram. “They have been secured in safe places and resistance tunnels.”

Video geolocated and authenticated by CNN shows at least one Israeli soldier being taken prisoner.

The video, posted to Hamas’ official social media accounts, shows militants yank two clearly terrified and stunned soldiers out of a disabled tank. It’s unclear from the video how the tank was disabled, but Hamas has used drones to drop bombs onto Israeli tanks before.

One of the soldiers is then seen in a short snippet of video being kicked on the ground by the militants. In the next clip, the soldier is seen lying motionless on the ground.

The second soldier is seen being led away by Hamas militants. A third soldier – his face very bloody – is seen lying on the ground motionless near the tank track. CNN does not know the current whereabouts or status of the three soldiers.

A second video, taken afterward, shows a number of different armed men around the tank. The three soldiers are nowhere to be seen.

The armed men are then seen pulling a fourth Israeli soldier from the tank. The soldier is motionless as he’s dragged down the side of the tank and onto the ground. The armed men are seen stomping on his body.
