The death toll in India's hydropower tunnel disaster rose to 25 as rescue teams recovered the last 13 trapped workers. A methane gas explosion at the Teesta Hydroelectric Project in Sikkim caused the collapse, prompting a four-day rescue effort hampered by toxic gas. A high-level committee was formed to investigate and recommend safety measures.

The death toll in India's hydropower tunnel disaster rose to 25 after rescuers recovered the last 13 trapped workers following a gas explosion. The incident occurred at the Teesta Hydroelectric Project in Sikkim, caused by methane gas buildup, with rescue efforts hampered by toxic conditions. A high-level committee was formed to investigate and recommend safety measures.

Toxic gas and water are hindering rescue efforts for 13 workers trapped in a collapsed hydropower tunnel in India's Sikkim state after a methane gas explosion killed 12 workers. Survivors described escaping during the blast, while rescuers struggle with hazardous conditions.

Toxic gas and water buildup are hindering rescue efforts for 13 workers trapped in a collapsed hydropower tunnel in India's Sikkim state, following a methane gas explosion that killed 12 workers. The incident occurred at the Teesta Hydroelectric Project in a seismically active region prone to tunneling risks due to fragile rock formations and trapped gases.

Toxic gas is slowing rescue efforts for 13 workers trapped in a collapsed hydropower tunnel in India after a methane gas explosion killed 12 workers. Rescue teams face challenges due to gas and water buildup at the Teesta Hydroelectric Project in a seismically active region.

Toxic gas is hindering rescue efforts for 13 workers trapped in a collapsed hydropower tunnel in India's Sikkim state after a methane gas explosion killed 12 workers. Rescue teams face challenges from gas and water buildup at the Teesta Hydroelectric Project site in a seismically active region with fragile rock formations.

A methane gas explosion in a tunnel under construction for the Teesta hydroelectric project in Sikkim, India, killed 11 people and left 14 missing, with rescue efforts hampered by toxic gases. The National Disaster Response Force (NDRF) is working to reach trapped individuals at the site, part of the National Hydroelectric Power Corporation (NHPC)-led project in a seismically active region.

A suspected gas explosion caused a tunnel collapse at the Teesta hydroelectric project in Sikkim, India, killing 10 and leaving 17 missing. Rescue efforts are hindered by toxic gases, and officials from the National Hydroelectric Power Corporation also became trapped during the operation.
