An avalanche slammed into a Pakistani military camp near the disputed Kashmir border with rival India on Saturday, burying more than 100 soldiers, with no sign of survivors 12 hours later, the army said.
The soldiers were trapped near the Siachen Glacier in the Karakoram mountain range.
"This avalanche hit a (military) headquarters. Over 100 soldiers and personnel are trapped," army spokesman Major-General Athar Abbas told Reuters, adding that a total of 117 soldiers were stationed there.
A helicopter rescue team was searching for survivors with sniffer dogs, he added.
"This happened at six o'clock. These avalanches usually happen at night. It took them by surprise," said Abbas.
Siachen is in the northern part of the Himalayan region of Kashmir.
Muslim-majority Kashmir is at the heart of hostility between India and Pakistan and was the cause of two of their three wars.
