Hamas fighters are holding as many as 150 people hostage in locations across Gaza following their raids on southern Israel Saturday, Israel’s ambassador to the United Nations said Monday.

Their presence is complicating Israel’s response to the militant group’s deadly attack, however Ambassador Gilad Erdan told CNN Monday that the government’s priority is destroying Hamas to restore security for all Israeli citizens.

“Of course, we want to see all of our boys, girls, grandmothers, everyone who was abducted we want to see them back home, but right now, our focus is looking at our national strategy is to obliterate Hamas terrorist capabilities,” he said.

In a chilling development earlier Monday, Abu Obaida, the spokesperson of Hamas’ Al-Qassam Brigades, said Hamas would start executing civilian hostages if Israel targets people in Gaza without warning.

Little evidence has emerged as to the condition of the hostages, some of whom have been identified by their families as they desperately seek answers.

Here’s what we know so far about those being held.

Music festival

Hundreds of attendees at the Nova music festival ran across the plains of the Negev Desert near Urim, a community close to the Gaza Strip, trying to escape Hamas gunmen pursuing them in vehicles in a terrifying chase. Some were killed and others were seized by armed captors, social media videos showed.

Details of hostages from the attack are beginning to emerge as family members recognize relatives in the clips circulating online.

In one video that went viral, an Israeli woman and her boyfriend – identified as Noa Argamani and Avinatan Or – were shown being kidnapped. In it, Argamani was hoisted onto the back of a motorcycle and driven away as Or was apprehended and made to walk with his hands behind his back. CNN could not independently verify the video.

“It’s very difficult when you see someone that is so close to you and you know so much being treated like this,” Amir Moadi, a roommate of Noa Argamani, told CNN, adding that he knew about five or six people who had been at the festival and have since gone missing.

In another video authenticated by CNN, an unconscious woman who was at the festival could be seen being displayed by armed militants in Gaza as onlookers shouted “Allahu Akbar.”

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

Ricarda Louk, Shani’s mother, told CNN that she last spoke to her daughter after hearing rockets and alarms sounding in southern Israel, calling to see if she’d made it to a secure location. Shani told her mother she was at the festival with few places to hide.

“She was going to her car and they had military people standing by the cars and were shooting so people couldn’t reach their cars, even to go away. And that’s when they took her,” Ricarda told CNN, adding that she hopes to see her daughter again, but the situation is
