A fire broke out at an auto parts factory in South Korea’s central city of Daejeon on Friday, injuring at least 55 people, with 14 others unaccounted for, authorities said.

Axar.az informs, citing Yonhap, a total of 170 workers were inside the plant when the blaze started, and 14 of them have been unreachable, officials said.

Of the injured, including 24 with serious injuries, many had inhaled toxic gas or fallen from the building, they said.

Of the two buildings making up the plant, one has completely burned down, while the other is still burning. Firefighters have not been able to enter the structure due to concerns it could collapse.

President Lee Jae Myung ordered authorities to mobilize all available resources to rescue the victims and contain the fire.
