An explosion at a Venezuela refinery plant has killed at least 39 people and injured 80 others.
The blast at the Amuay plant, one of the world's largest, has also halted production for at least two days and damaged the surrounding houses, according to BBC News. The fire has since been brought under control.
"The gas cloud exploded, igniting at least two storage tanks and other facilities at the refinery," Energy Minister Rafael Ramirez told state TV. "It was a significant explosion, there is appreciable damage to infrastructure and to houses opposite the refinery."
Venezuelan leader Hugo Chavez declared three days of national mourning for the victims of the explosion, BBC News reported.
"I want to send out to the families of those who died, civilians and military, all our pain, mine, that of all my family, everyone in the national government and the people of Venezuela," Chavez said. "It has been decided to have three days of mourning, national mourning because this affects everyone in the big family of Venezuela."
Among the victims of the explosion, which was caused by a gas leak that ignited, was a 10-year-old boy, the Los Angeles Times reported. 18 of the victims were National Guard troops stationed at the refinery, and 15 were civilians, according to BBC. Six bodies have still not been identified.
