Rescue teams are trying to reach 13 workers trapped inside a collapsed hydropower tunnel in northeastern India following an explosion at the project, according to multiple reports. Authorities say the tunnel incident has left workers inside the wreckage and that access is being delayed by hazardous conditions. Several outlets report that toxic gas is hampering rescue efforts, forcing responders to slow down and manage air-safety risks before they can reach the trapped group.
Time.com reports that the explosion has already resulted in 12 deaths, in addition to the 13 workers believed to be trapped. The other sources describe the same core facts: a hydropower tunnel collapse caused by an explosion, 13 workers still inside, and rescue operations affected by toxic gas. While details of the exact gas type or the rescue methods are not provided in the excerpts, the coverage consistently indicates that the presence of toxic fumes is a key factor preventing immediate entry into the tunnel. Authorities continue rescue and recovery operations as conditions allow.
