A fire swept through a bar in the northern French city of Rouen overnight, killing 13 people and injuring six, after a birthday cake with candles and sparklers fell to the floor and set the carpet ablaze, police said. The fire broke out in the basement of the popular Cuba Libre bar and quickly engulfed the room where some 20 people were celebrating, filling it with thick black smoke and poisonous fumes, a Rouen police officer told Reuters. "A large number of those who died were killed by the fire, others were overcome by the toxic fumes," the officer said.
