A gas explosion caused a tunnel collapse at a hydroelectric project in the northeastern Indian state of Sikkim, killing at least 20 workers and leaving several others trapped, according to officials. The incident occurred on Monday at the 500-megawatt project being developed by the state-owned National Hydroelectric Power Corporation (NHPC) on the Teesta River, near the village of Samardung, close to the border with Bhutan and Tibet.

Coverage Comparison

Initial reports from Al Jazeera and the BBC put the death toll at 10 and 12, respectively, with 17 and 13 workers missing or trapped. Later reporting from Al Jazeera raised the death toll to at least 20, with 13 bodies recovered. The Jerusalem Post and South China Morning Post, citing Reuters, reported 10 killed and 15 feared trapped. The BBC reported that 27 people were working inside the tunnel, of whom two escaped and 25 were trapped.

Rescue operations, involving the National Disaster Response Force (NDRF), have been hampered by hazardous conditions inside the tunnel, including toxic gases and flooding. Officials have said that survival chances for those still trapped are slim.

Key Claims

  • At least 10 workers were killed in a blast caused by a suspected gas leak in a tunnel at a hydroelectric project in Sikkim, as reported by Al Jazeera, the BBC, the Jerusalem Post, and the South China Morning Post.
  • The blast was caused by a sudden burst of gas suspected to be methane trapped or embedded in rocks in the tunnel, according to NHPC statements cited by multiple outlets.
  • The tunnel is part of a 500-megawatt hydroelectric project for the state-owned NHPC on the Teesta River, as reported by Al Jazeera, the BBC, the Jerusalem Post, and the South China Morning Post.
  • Rescue efforts have been hampered by hazardous conditions, including toxic gases and flooding in the tunnel, as reported by Al Jazeera.
  • The death toll has risen to at least 20 people, with 13 bodies recovered, according to Al Jazeera's later report.
  • Construction accidents are common in India, especially in the Himalayan region, due to seismic activity and unpredictable underground conditions, as reported by Al Jazeera.
  • Fifteen Indian workers were feared trapped after the blast, as reported by the Jerusalem Post and the South China Morning Post.
  • Survival chances for the trapped workers were slim due to hazardous conditions, as reported by the Jerusalem Post and the South China Morning Post.

Perspectives

NHPC (National Hydroelectric Power Corporation)

The state-owned corporation said the tunnel's collapse was triggered by an "explosive release of suspected methane gas trapped/embedded in the rocks," resulting in dense smoke and toxic gases. It said a detailed investigation would be conducted.

Sikkim State Disaster Management Authority

Director Rajiv Roka said rescue efforts were hampered by waterlogging and methane gas leaking from underground rock formations, making it difficult to retrieve bodies. He expressed doubt that any survivors would be found.

Sikkim Government

In a separate statement, the Sikkim government attributed the accident to "methane gas combustion." Chief Minister Prem Singh Tamang has set up an investigation team, as reported by the BBC.

NDRF (National Disaster Response Force)

NDRF officials on site reported finding toxic gases such as methane, carbon monoxide, and hydrogen sulphide inside the tunnel, and said rescuers were using specialized breathing equipment. The NDRF also said the incident occurred about 1.5 kilometers inside the tunnel.
