Toxic Gas Hampering Rescue of 13 Trapped in Sikkim Tunnel Collapse

Detroit, MI, July 22, 2026 —
Rescue operations for 13 workers trapped in a collapsed hydropower tunnel in India’s Sikkim state are being significantly hampered by the presence of toxic gas.
The tunnel, part of the Teesta Hydroelectric Project, collapsed following a gas explosion that occurred two days prior to the latest incident. That initial explosion resulted in the deaths of 12 other workers.
The toxic gas poses a severe threat to both the trapped individuals and the rescue teams attempting to reach them. Efforts to clear the gas and safely access the tunnel are ongoing, but the challenging environmental conditions are slowing progress.
Details regarding the specific type of toxic gas and the exact timeline of the ongoing rescue efforts were not immediately available. The Teesta Hydroelectric Project is a significant infrastructure development in the region.
