MORE than 100 Pakistani soldiers were buried by an avalanche near the Siachen glacier on the border with India on Saturday, an army spokesman said.
Several Pakistani television channels have reported that about 150 soldiers were trapped.
"At six o'clock this morning this avalanche hit a (military) headquarters. Over 100 soldiers and personnel are trapped," said the spokesman, Major-General Athar Abbas, adding that rescue teams were heading to the scene.
He said the army would comment later on whether there were any casualties.
The avalanche was in the glacier's Gayari sector at 5.45 am on Saturday.
Siachen is on the northern tip of the divided Kashmir region claimed by both India and Pakistan.
The two neighbouring countries have deployed troops facing each other at elevations of up to 6,700 metres (22,000 feet) there.
There have been intermittent skirmishes since 1984, and the region is known as the world's highest battlefield. More soldiers have died from the harsh weather than combat.
