New photoes have emerged which shows moments before the ceiling of a Swiss bar caught fire.
The blaze killed around 40 people and injured 115 - Swiss police are working to identify the victims. Officers warn the process could take days or weeks.
French and Italian authorities say they have citizens missing, including 16-year-old Giovanni from Bologna. Footage has also emerged showing a partygoer attempting to put out flames.
At a hospital in Geneva, a doctor says patients, some as young as 15, are being treated for severe burns. More than 24 hours after the fire, forensic teams remain at the scene where a vigil took place last night, say reports.
Eyewitnesses described chaotic scenes as fire spread through bar, with one saying: “We've heard from a number of eyewitnesses and people who were in the bar at the time of the fire.
"People were running in all directions, screaming and crying. A young man came up to me and said he'd seen hell - things he would never forget."
One 18-year-old, who did not want to give his name, said he entered the bar during the fire to search for his little brother. "I saw people burning... I found people burning from head to foot, no clothes anymore," he said.
Axel Clavier said he was trapped in the burning building and had to break a window to escape. He told AFP: "We couldn’t see because of the smoke.
“Half of my clothes were gone. It was crazy."
He said that before the fire started there were waitresses in the bar with champagne bottles with flares too close to the ceiling and the fire took hold suddenly. Two French women who were inside the bar when the fire also said they believe it began when a waitress put "birthday candles" on top of some champagne bottles.
They told French media outlet BFMTV “the entire ceiling was ablaze” within seconds as the flames “started to rise very quickly”. It is not yet clear what caused the fire, but eyewitnesses have described the speed at which it spread, and the chaos that ensued.
