Forty-one workers remained trapped in a collapsed road tunnel in northern India for a seventh day as a new drilling machine arrived on site to replace the damaged one.
The nature of the exceptionally hard rock formation in the area coupled with the clearing of debris damaged the original machine and paused rescue efforts on Friday, according to officials. This added a new challenge to the long-drawn rescue efforts.
