Rescue efforts are underway in India to save eight workers trapped in a tunnel collapse in the southern state of Telangana. The workers have been underground for four days with no contact made by rescuers.
The **Srisailam Left Bank Canal** tunnel collapse occurred on Saturday, and despite the involvement of several agencies, including the Indian Army and the National Disaster Response Force, rescuers have faced repeated setbacks due to loose soil and mud inside the tunnel.
