Death toll from blast at Indian hydroelectric project rises to 20 people

The death toll from a gas explosion and tunnel collapse at a hydroelectric project under construction in Sikkim, India, has risen to at least 20 people. Rescuers have recovered 13 bodies and have seen an additional seven to eight bodies inside the collapsed tunnel, but have been unable to retrieve them due to flooding and toxic methane gas. The explosion was reportedly triggered by a release of suspected methane gas trapped in the rocks. Rescue efforts for the 25 workers trapped in the tunnel have been severely hampered by these conditions, leading officials to believe there are no survivors. The National Hydroelectric Power Corporation (NHPC) is overseeing the project and stated a detailed investigation will be conducted.

Tunnel collapse in India kills 12 workers

At least 12 workers have died following a gas explosion and subsequent collapse in an under-construction tunnel in Sikkim, India. The incident occurred approximately 1.5 kilometers inside the tunnel, which is part of a hydropower project developed by the National Hydroelectric Power Corporation (NHPC). Officials stated the explosion was caused by the combustion of suspected methane gas trapped within the rocks. Twenty-seven workers were inside the tunnel at the time; two escaped, and 25 were trapped. Rescue operations are ongoing to locate the 13 workers still missing, but hazardous conditions are hindering efforts.

India tunnel collapse at a hydropower project kills 10 as 17 remain missing

A suspected gas explosion, possibly methane, triggered a tunnel collapse at a hydropower project in Sikkim, India, on Monday. The incident occurred at the Samardung village site, where workers were engaged in construction for the state-owned National Hydroelectric Power Corporation. At least 10 individuals have died, and 17 others remain missing, including six NHPC officials who entered the tunnel to aid in rescue efforts. Rescue teams are facing hazardous conditions, including toxic gases like methane, carbon monoxide, and hydrogen sulphide, which are hindering their search for survivors.

India tunnel blast kills 10 workers, leaves at least 15 trapped

Ten workers died and at least 15 are feared trapped following a blast in a tunnel at a hydroelectric project in Sikkim, India. The incident occurred on Monday at a state-owned National Hydroelectric Power Corp (NHPC) project on the Teesta river in the village of Samardung. Authorities suspect a gas leak, possibly methane trapped in rocks within the tunnel, caused the explosion and released dense fumes and toxic gas. Rescue efforts are underway for those still trapped.
