At least eight Indian soldiers died when an avalanche hit their barracks in Indian-administered Kashmir.
The paramilitaries of the Indo-Tibetan Border Police were guarding the Jawahar tunnel about 200km (130 miles) north of state winter capital, Jammu.
Sunday night's avalanche buried the paramilitary barracks near the tunnel, which connects the Kashmir valley with the Jammu region.
India has more than 200,000 soldiers deployed in the Kashmir valley.
Militant separatists have been fighting Indian rule in Kashmir, which is claimed by both Pakistan and India, since 1989. About 40,000 people have been killed in the fighting.
Rescue work is continuing at the avalanche site.
This winter's snowfall in southern Kashmir is said to the heaviest for five years.
