BUENOS AIRES, Argentina - A flare lit during a rock concert ignited the foam ceiling of a Buenos Aires nightclub packed with teenagers, starting an inferno that killed 175 people, many of them teens, and injured more than 600, officials and witnesses said Friday.
An emergency exit in the building was believed to have been locked to prevent people from coming in without paying — leaving the club's main entrance as the only way in or out, said Buenos Aires Mayor Anibal Ibarra.
