China's state news agency says a coal mine explosion has killed 18 and injured 12 in the northeast part of the country.

The Xinhua News Agency cites local authorities as saying the Saturday afternoon blast occurred in Helong city in Jilin province.

The report says rescue work has ended, but an investigation into the cause of the explosion continues.

China's mines are the deadliest in the world. Safety has tightened in recent years, but regulations are often ignored.
