A coal mine fire killed 24 workers and injured 52 others in northeast China's Liaoning province early on Wednesday, the state-owned Liaoning Fuxin Coal Corporation told Xinhua.

The fire occurred in a coal mine under Hengda Coal, a subsidiary of Fuxin Coal, a major coal producer in the province.

Fuxin Coal said the rescue operation was over and all the injured workers have been hospitalised.

Hengda Coal has halted operations in all its mines for safety checks. The company employs more than 4,600 people.

Last year, eight workers were killed in gas leaking in a mine under Fuxin Coal.
