More than 15 Indian workers trapped after hydroelectric tunnel blast kills nine

Rescue teams are struggling to reach trapped workers as toxic gas and water slow operations, officials said.

  • A methane explosion at the 500-megawatt Teesta Hydroelectric Project in Sikkim killed 20 workers on Monday, leaving five trapped at the Samardung-Jholungey site about 40 kilometers from Gangtok.
  • The Teesta River basin features fragile rock formations riddled with fractures that trap ancient gases, making tunneling in this seismically active Himalayan region inherently hazardous.
  • National Disaster Response Force personnel struggle to enter the tunnel due to toxic gas and water buildup, while most victims were migrant laborers from West Bengal and Punjab.
  • Sikkim Chief Minister Prem Singh Tamang ordered a special investigation, while Prime Minister Narendra Modi announced Rs 400,000 compensation for each victim's kin, stating, "I extend my deepest condolences to the bereaved families."
  • Tamang described this as India's worst tunnel incident since the 2023 Silkyara collapse, where 41 men were trapped for 17 days, as scientists warn that climate-driven glacial retreat increases construction risks.
