4 killed, 9 missing in China's coal mine accident

The cause of the explosion was unclear, while rescue work was underway, it said.

At least four persons were killed and nine others remain missing in a coal mine accident in China's Guizhou province, official media reported.

The coal and gas burst happened yesterday at 9.10 pm in the Zimujia coal mine in Guizhou's Panzhou city, state-run Xinhua news agency reported.

The cause of the explosion was unclear, while rescue work was underway, it said.

Mining accidents are common in China. However, the number of deaths have reduced at mines in recent years.

In June this year, a powerful explosion in an iron mine in country's northeast Liaoning province claimed the lives of 11 people and left nine others injured.

Similarly, in May, a methane gas explosion ripped through a coal mine in central China's Hunan province, killing at least five workers.
