Pakistan officials say an avalanche has smashed into a military base, burying more than 100 soldiers.

Military authorities say the avalanche hit the base Saturday in the mountainous Siachen Glacier region, known as the world's highest battlefield. Pakistan and India have military outposts in the region.

Officials say rescue teams are headed to the remote base in the Himalayan area near India.

Pakistan's military says the fate of the soldiers was not immediately clear.

Military experts say Siachen's inhospitable climate and avalanche-prone terrain have claimed more lives than gunfire.
