Rescuers in southern China have recovered the body of one of the 123 miners trapped in a flooded coal mine, and are holding out little chance any others will survive.

The miners have been trapped in the Daxing mine at Xingning in Guangdong province since Sunday. State media say that so far rescuers have been unable to find the source of the flooding.

Chinese police have arrested 11 people for their roles in the disaster, including the mine's owner, manager, board chairman and chief technician.

The government also has suspended the mayors of the cities of Xingning and Meizhou for failing to supervise coal mine production.

China has the most dangerous mines in the world. More than 2,700 miners have been killed in the first half of this year alone.
