Indian rescue workers try new shaft after drilling stalls near trapped men

Efforts to free 41 workers stuck in tunnel for almost two weeks hit another setback as earth-boring machine breaks down

Indian rescue workers have brought in a new digging machine to open a vertical shaft to free 41 men trapped inside a collapsed road tunnel, after efforts via another route hit a snag metres away from them.

In the latest setback in attempts to rescue the increasingly desperate workers, who have been trapped for almost two weeks, engineers driving a metal pipe through 57 metres (187ft) of rock and concrete ran into metal rods and construction vehicles buried in the earth.
