Eyewitnesses have been describing the nightmare they witnessed after a fierce fire broke out at a bar earlier this week, leaving dozens dead and others injured.

“I thought my little brother was inside so I came and tried to break the window to help people to exit, and after that I went in,” an 18-year-old man said, according to the . “I saw people burning… I found people burning from head to foot, no clothes anymore,” he remembered, adding, “It was very shocking.” 

The man’s brother was unharmed, the outlet said.

“I went in this bar every day this week — the day I didn’t go, it burned,” he told the outlet.

A woman named Daniella was returning home with her husband after a dinner when she saw some of the , the BBC reported.

“People were running in all directions, screaming and crying. I saw several people being carried out on stretchers,” she told the outlet. “A young man came up to me and said he’d seen hell — things he would never forget. And then I just froze.”

Gianni Campolo, 19, went to the bar to help first responders after receiving a call from a friend who had escaped the fire, according to the .

“I have seen horror, and I don’t know what else would be worse than this,” Campolo told TF1, as reported by the AP.

Ferdinand Du Beaudiez, a 19-year-old who escaped from the in the bar, said he went back inside to search for his brother, girlfriend and others, explaining he “couldn’t think to let them stay in the fire when I was alive outside.” 

He said the first time he went back in, he found someone “laying in the stairs” who “was completely burned, clothes were burned”—he couldn’t tell if the person was a man or woman. He “slid” the person “on the ground, and he was being taken care of, um, outside …” the survivor remembered. 

The second time he went back in, he encountered “more smoke” and “could breathe less,” he said, adding he “went in, couldn’t see anything and went straight out.”

He eventually located his girlfriend, who told him where his brother was.
