India rescuers make painstaking progress towards 41 trapped in tunnel

 Indian rescue teams crept forward Tuesday in a painstaking dig by hand through rock and rubble towards 41 workers who have been trapped in a collapsed road tunnel for 17 days.

 

Soldiers and skilled miners are using a so-called "rat-hole" mining technique to clear the final stretch, digging through some two metres (six feet) of rubble to leave only an estimated seven metres (23 feet) to go.
