Sixteen soldiers died as an Army truck fell into a gorge in North Sikkim on Friday morning.
The truck carrying the soldiers skidded off the road in a mountainous area. The truck was part of a three-vehicle convoy that had started from Chatten towards Thangu in the morning.
At Zema, the vehicle skidded down a steep slope while negotiating a sharp turn, Army officials said.
A rescue mission was immediately launched and four injured soldiers were evacuated.
