Tunnellers trapped underground when a rail tunnel under construction in China collapsed on Monday have been confirmed as alive and work is underway to rescue them.
The cause of the collapse of the tunnel in Yunnan, which trapped 14 workers underground, is unknown at this stage.
The tunnel, in Funing County, links Yunnan province with neighbouring Guangxi region and is part of the central government’s Go West funding initiative.
The tunnel which failed is known as the Funing No 1 tunnel, which is part of a new 710km railway linking Kunming with Nanning, the capital of Guangxi, which is due to be complete in 2016.
Construction work on the Yunnan section is worth ¥ 7.87bn (£741M) and is being undertaken by China Railway First Group and Tunnel Group, a subsidiary of China Railway Group. The contact for the work was awarded in 2010.
