A tunnel under construction in Uttarakhand, northern India, collapsed due to a landslide, killing at least seven workers and injuring 13 others. Officials confirmed the incident occurred late Thursday, with rescue operations continuing as of Friday. The site, operated by the Tehri Hydro Development Corporation, was part of a state-run hydropower project. At least three workers remain missing, while 19 were successfully rescued.

The collapse sent water and debris into the tunnel, creating dangerous conditions for those inside. Emergency services responded swiftly, but the scale of the disaster highlights the risks of construction in mountainous regions. The State Disaster Management Authority is coordinating the response, emphasizing the need for safety measures in such projects.

Authorities have not yet released details on the cause of the landslide, though preliminary reports suggest heavy rainfall may have contributed. The incident has raised concerns about worker safety in ongoing infrastructure projects. Rescue teams continue to search for the missing, with efforts focused on stabilizing the site and ensuring the safety of remaining workers.

The tragedy underscores the challenges of working in remote and geographically complex areas, where natural disasters can quickly turn construction sites into disaster zones.
