Rescuers are racing against time to bring out the eight workers trapped for over 48 hours in a collapsed tunnel in Telangana. A state minister has warned that their survival chances are "very, very remote" as a pileup of muck and water hinders the rescue mission.
The tunnel, proposed to be 44-km-long - behind the Srisailam dam in Nagarkurnool collapsed Saturday morning when some workers were inside repairing a leak. While most of them managed to escape, eight got trapped and have been out of contact since Saturday.
