Three people have been killed and another injured after a fire broke out at a chemical plant in China's Inner Mongolia Autonomous Region.
The blast happened at about 3:30 a.m. local time on Thursday (1930 GMT on Wednesday) at Jilantai Chlor-Alkali Chemical Plant in Alxa League.
Three workers died on the spot while another sustained serious wounds, Xinhua news agency reported on Thursday.
The chemical plant is a subsidiary of the China National Salt Industry Corporation.
Firefighters have been mobilized to the site to put out the fire. Ambulances also shifted the bodies and those wounded to nearby hospitals.
The cause of the explosion is still under investigation, local safety authorities said.
On November 20, three people were killed and dozens of others injured after a fire broke out at a chemical plant in China's northern province of Shanxi.
The blast took place at the Yushe Chemical Industry Co. Ltd. in Jinzhong City. The powerful shock wave released by the explosion shattered windowpanes of a number of surrounding buildings.
An average of 187 Chinese workers have lost their lives on an almost daily basis in job-related accidents in the first half of this year.
