Siachen: Indian and Pakistani forces have faced off across the Siachen glacier in the Himalayas, known as the world's highest battlefield at 5,500 meters (18,000 feet) above sea level, since 1984. The two sides have been trying to find a solution that would allow them to withdraw troops but India says it is unwilling to bring its forces down until Pakistan officially authenticates the positions they hold. Pakistan has said it is willing to do so but on the condition that it is not a final endorsement of India's claim over the glacier.
