A fire and explosion in a Bucharest nightclub killed 27 people and injured 155 during a rock concert that featured fireworks late on Friday, Romanian government officials and witnesses said.
In one of the capital's worst disasters in decades, about 400 people, mostly young adults, stampeded for the exit as the club in the basement of a Communist-era factory filled with smoke.
Several witnesses said there were fireworks inside the club. Colectiv Club's Facebook page said the show would feature pyrotechnic effects.
A pillar and the club's ceiling went up in flames and then there was an explosion and heavy smoke, the witnesses said.
TV footage showed police officers and paramedics trying to resuscitate young people lying on the pavement while sirens wailed with more ambulances deployed to the scene.
"There was a stampede of people running out of the (Colectiv) club," a man who escaped without shoes told Reuters.
