Indian rescuers have drilled three-quarters of the way through debris towards 41 workers trapped in a collapsed road tunnel for the past 11 days, say officials , raising hopes of a breakthrough with diggers in the final stretch. Engineers are working to drive a steel pipe through at least 57 meters of the tonnes of earth, concrete and rubble that has divided the trapped men from freedom since a portion of the under-construction tunnel in the northern Himalayan state of Uttarakhand collapsed 11 days ago.
