Authorities in India said on Monday they were set to begin manual digging of what they hoped was the final phase of rescuing the 41 construction workers trapped in a collapsed mountain tunnel in the country's north for over two weeks.
This came a day after an attempt to drill vertically — an alternate plan to digging horizontally from the front — started, with the newly replaced drilling machine excavating about 20 meters (nearly 65 feet), according to officials.
