Authorities said a narrow opening has been made to pass oxygen into the tunnel as personnel of several teams work on to rescue the trapped workers.

The under-construction tunnel of the Navayuga company from Silkyara to Dandalgaon on the Yamunotri National Highway collapsed at 5 a.m. on Sunday.

At least 36 labourers are trapped in the tunnel, and they have been stuck for more than 30 hours.

Rescue efforts by personnel from multiple agencies, including the National Disaster Response Force (NDRF), State Disaster Response Force (SDRF), fire brigade, have been going on since Sunday morning.

According to the information, the accident happened at a distance of 200 meters from the tunnel entrance towards Silkyara, while the workers were 2,800 meters inside the entrance.
