tunnel collapse

A tunnel collapse at a hydropower project in India's northeastern state of Sikkim has resulted in the deaths of at least 10 people, with 17 others still trapped. The incident, believed to have been triggered by a suspected gas explosion, occurred on Monday at the Samardung viaduct. Rescue operations have been severely hampered by hazardous conditions within the tunnel, including toxic gases, making it difficult for teams to reach the trapped individuals. The collapse highlights the dangerous nature of tunnel construction, particularly in challenging environments. The ongoing rescue efforts and the high casualty count make this event a significant and tragic development in the region.
