MONTREAL, Quebec — A massive explosion at a fireworks warehouse killed two workers Thursday, police said, leaving a huge plume of smoke blanketing an area west of Montreal.
A series of explosions spread from the charred building after the initial blast at B.E.M. Fireworks near Valleyfield, Quebec. Images from the scene showed a building near a major highway completely destroyed.
Provincial police said two bodies were found in the wreckage but they did not identify them.
Nearly two hours after the blast, fireworks could still be heard exploding at the scene of the fire that continued to burn out of control hours after the explosion, according to witnesses.
Local fire chief Stephane Massicotte said since the warehouse was filled with pyrotechnics it was difficult to battle the blaze.
"This caused a huge amount of flames and very intense heat," Massicotte told reporters.
He said 150 firefighters were used to battle the flames, which were under control by early Thursday afternoon. Reporters on the ground also indicated that there were no fire hydrants in the vicinity.
"All of a sudden I heard, 'boom, boom, bang,'" Mario Cramerstetter said from his office, which is just over a mile (1.6 kilometers) away from the site.
