Rescuers have drilled into the rubble of a collapsed road tunnel in northern India to fix wide pipes for 40 workers trapped underground for a sixth day to crawl to freedom.

Drilling with a new machine started on Thursday and had covered a stretch of 78 feet by Friday morning, Devendra Patwal, a disaster management official, said.
