The six-man team, including members of the Army, Navy and RAF, have been trapped in the Alpazat cave system for more than eight nights.

They are part of a 12-strong Combined Services Caving Association expedition, Cuetzalan Tiger 2004. Six, including group leader Major Steve Whitlock, remain above ground.
The trapped group are said to be hoping water levels will soon drop …
