A tunnel collapsed January 29 during construction at the 390-MW Dulhasti hydroelectric project, killing two workers and injuring 13 others.
Government broadcast services said the tunnel collapsed about 2 a.m., resulting in the casualties and flooding the Kishtwar area of Doda District in Jammu and Kashmir State.
A two-hour rescue operation resulted in the 13 injured being hospitalized. Three seriously injured workers were airlifted to a Jammu hospital.
National Hydroelectric Power Corp. had been nearing completion of the project, with on-line ceremonies expected in March on the Chandra River.
