Rescue teams in northeastern India are facing dangerous conditions as they try to reach 13 workers trapped inside a tunnel following an explosion at a hydropower project. The incident has already left 12 people dead, adding urgency to an operation complicated by hazardous air inside the passage.
According to reports from the scene, the blast took place about 1.5 kilometers inside the tunnel. Officials involved in the response said carbon monoxide has been detected, making it difficult for emergency crews to move deeper into the site and safely carry out rescue work.
The presence of toxic gas has become a major obstacle for teams attempting to access the trapped workers. Emergency personnel are working under high-risk conditions as they assess how to proceed without exposing rescuers to the same dangers inside the tunnel.
The accident has drawn attention to safety risks at major infrastructure and energy projects, especially in enclosed underground worksites. With fatalities already confirmed and workers still unreachable, the rescue effort remains focused on overcoming the toxic conditions inside the tunnel.
