An explosion at a steel mill in China`s northeast killed four people and left five hospitalised with injuries, the city government said on Friday.
A blast furnace exploded Thursday morning at the Yingkou Iron and Steel Co., Ltd. in Yingkou, east of Beijing in Liaoning province, the city`s Emergency Management Bureau said in a statement.
The cause was under investigation, but experts believe an equipment malfunction was to blame, the announcement said.
Phone calls to the Yingkou government on Friday weren`t answered.
The disaster occurred less than 12 hours after an explosion Wednesday evening blamed on cooking gas killed 31 people in a barbecue restaurant in Yinchuan, a city in China`s northwest.
