Trapped Chinese men file footage of plight

Authorities in China are trying to reach three men trapped underground after the rail tunnel they were working on collapsed.

Despite being cut off for more than a week, they have been in touch with their rescuers, sending out footage of themselves as they try to dig their way out.

The plan to rescue them is to widen a narrow water pipe that runs below the collapsed tunnel .

The authorities have co-ordinated their digging with the trapped men so that they reach each other in the next two days.
