TAIYUAN, Aug. 16 (Xinhua) -- One person was killed and 140 injured, including 27 children, after a gas leak at an iron and steel company in north China's Shanxi Province Wednesday morning.

The gas leak at Shanxi Haiwei iron and steel company in Wenshui County, the city of Lyuliang, occurred at 5:30 a.m. Wednesday, causing the death of a 66-year-old in Sangcunying village.

One person in serious condition received treatment in Taiyuan, the capital city of Shanxi, while other injured people were taken to a local hospital.

The incident is thought to have been caused by fallen steel plates from the pipelines. Workers were working around the clock to repair the leak Thursday afternoon.
