China arrests over explosion at 'gambling spot'
Chinese police have arrested eight people over an explosion at a village in Guizhou province that killed at least 15 people, state media report.
The explosion took place on Monday afternoon at a remote mountain slope at a village in Kaili City, Xinhua said. Eight people were reportedly injured.
The blast is thought to have taken place at an illegal gambling site on the hill, Xinhua said, citing police.
Police are investigating the cause of the explosion.
Initial investigations suggested the blast was "a man-made criminal case", state-run newspaper Global Times reported, citing the local publicity department.
"I arrived the accident site with policemen at about four o'clock. I saw the tent was totally damaged in the explosion," a relative of one of the injured people told state broadcaster CCTV.
At least five of those injured were sent to a nearby hospital.
Jiang Xiaohai, director of plastic surgery at the Southeast Qian People's Hospital, told CCTV that the injuries were mostly caused by fragments from the blast and some by big rocks.
Gambling is illegal in mainland China.
