"People were burning alive"; The most terrifying scenes, the footage is disturbing VIDEO

One woman called it "one of the worst scenes she's ever seen in her life," while an injured girl said she heard screams and wails from people trapped inside the tent.

One man said he "broke down" because "there was nothing he could do" to help those who were burned. The strike hit the al-Aqsa hospital complex in Deir al-Balah, central Gaza, in the early hours of Monday morning, causing a fire that burned makeshift shelters for displaced and injured people in Gaza.

At least four people were killed and dozens injured, mostly women and children, the Hamas-run health ministry said.

Horrifying footage of helpless people burning in flames as others try unsuccessfully to help them out of their tents is being shared on social media. Due to the disturbing content, the video is not attached to the text, but you can watch it HERE at your own risk.

The Israeli military said it targeted Hamas fighters operating inside a command center in the parking lot, which caused the fire "probably due to secondary explosions."

The strike hit an area between buildings with makeshift shelters, near an outpatient waiting room, which was empty at night, said Anna Halford, Medecins Sans Frontières (MSF) emergency coordinator in Gaza.

Halford was not in hospital during the Deir al-Balah attack. Hiba Radi, a woman who lived in a tent behind the hospital, said she was awakened by the sound of "explosions and fires breaking out around the tent."

"There were explosions everywhere, and we were shocked, wondering if it was gas or weapons," she said.

"This is one of the worst scenes we have witnessed and experienced," she added.

"We've never seen this kind of destruction before. It's hard, really hard," she added.

Atia Darwish, a photographer who captured some of the footage circulating, told the BBC it was a "huge shock" and he "couldn't do anything" as he watched people burn.

"I was completely devastated," he said.

Um Yasser Abdel Hamid Daher, who also lives at the hospital, told the BBC: "We saw so many people burning."

Among the injured are her son, his wife and children. Her granddaughter Lina (11), who received shrapnel in her arm and leg, said she heard people screaming.

"The daughter of our neighbors got a head injury, and her father died. Our other neighbors also died. The people next to us tore down the tent to get us out," she said.

Her grandmother added that the family "lost their tent and everything they had was left with nothing."

MSF announced last night that at least five people were allegedly killed and 65 injured. Of the forty injured, 22 men, eight women and 10 children remained in Al-Aqsa Hospital, while the rest were transferred to other hospitals, and eight were referred to the specialist burns department.

Ms Halford said her colleagues were treating burn victims "who are almost certainly not going to survive", adding that "there is very little you can do for burn victims of that severity".

Monday's strike was the seventh Israeli attack on the hospital since March and the third in the past two weeks, Halford added.

The acting head of the UN Office for the Coordination of Humanitarian Affairs said the attack took place in an area where residents of northern Gaza had been told to relocate.

There really is no safe place for people in Gaza," the statement said.

The humanitarian organization Médecins Sans Frontières (MSF), whose staff work in Al-Aqsa, told the BBC it did not know about the Hamas center and said "the hospital is functioning as a hospital".

The UN humanitarian agency said in a statement that "people were burned to death" and that "the atrocities must stop", while the spokesman for the White House National Security Council called the video "disturbing".

"Israel has a responsibility to do more to avoid civilian casualties, and what happened here is appalling, even if Hamas was operating near the hospital in an attempt to use civilians as human shields," the White House said.
