A fire at an auto parts factory in South Korea’s central city of Daejeon injured at least 55 people on Friday, with officials warning the toll could rise. The National Fire Agency said 24 were seriously hurt in a blaze likely caused by an explosion. Officials could not immediately confirm whether any of the injured were in life-threatening condition. Nam Deuk-woo, fire chief of the city’s Daedeok district, said authorities were searching for at least 14 others believed to have been inside the facility when the fire broke out. Videos and photos from the scene showed thick gray smoke billowing from the complex and some workers jumping from a building.
