DAEJEON, Feb. 14 (Yonhap) -- Three are dead after a chemical factory run by a major conglomerate exploded and caught fire, firefighters said Thursday.
The explosion occurred at 8:42 a.m. at a Hanwha factory in Daejeon, a city located about 143 km south of Seoul.
Three employees have been confirmed dead, the authorities said, with no further details known yet about the victims.
The factory caught fire shortly after the explosion, they said. Firefighters mobilized over 40 fire vehicles and put out the blaze in about an hour.
Fire authorities are investigating to determine the exact cause.
The same factory reported an explosion in May last year, in which two people were killed and five others wounded.
