Indian authorities on Tuesday said they were close to saving 41 workers who have been trapped under the rubble of a collapsed tunnel for 16 days, after a long rescue effort punctuated by repeated setbacks.
An ambulance was sent into a pathway created by excavators, as a trial to see how far it could get to the trapped men. Rescue workers have dug more than 55 metres into the rubble, leaving them an estimated few metres away from the people awaiting rescue.
