At least three workers remain trapped after a tunnel collapse in Chamoli, Uttarakhand, while rescue teams have brought more than a dozen others to safety, officials said. Water gushed into the tunnel and debris blocked the exit, complicating the rescue effort. Sixteen workers had been rescued until now, according to a report by Hindustan Times, while NDTV quoted District Magistrate Gaurav Kumar as saying 14 to 15 workers had been rescued. The discrepancy in the number of rescues has not been immediately resolved. A search and rescue operation is underway to evacuate the remaining three workers. The incident occurred in the Chamoli district of Uttarakhand, a mountainous region in northern India. Officials are coordinating efforts to reach the trapped workers, but no further details about their condition have been released. The collapse has raised concerns about safety at the site, though authorities have not yet commented on the cause of the incident. More information is expected as the rescue operation continues.
