At least six soldiers of the Indian Army were killed and more than 450 trapped on Monday when a massive avalanche struck a high altitude warfare training camp in Jammu and Kashmir's Baramulla district.

"A massive avalanche rolled down in the Khilanmarg mountain, engulfing a high altitude warfare camp set up by the army there. About 70 soldiers have been rescued so far from under the avalanche debris," a defence official said.
