Uttarkashi tunnel rescue op: Auger machine snag stops work but team is positive, says tunneling expert

The drilling work at Uttarkashi's Silkyara tunnel to evacuate 41 trapped workers was halted again on Thursday night after the augur machine encountered a technical snag. Till now, rescuers have drilled up to 46.8 meters in the Silkyara tunnel. "Currently, the machine is being repaired, which will take a few hours. If no other problem arises, the rescue operation will possibly resume tomorrow morning after 9 am," an official said.
