In pictures: Siachen, the world's highest battlefield

The Siachen glacier and the Saltoro ridge

The Siachen glacier is regarded as the world's highest battlefield. India and Pakistan both claim the area and have thousands of soldiers stationed there. Photographer Prashant Panjiar was given rare access to the Indian side in 2005, when he took these photos, most of which are being published for the first time.

The glacier has been in the news recently with the deaths in April of about 140 people, most of them soldiers, on the Pakistani side in an avalanche. Soon after, Pakistan's army chief said Pakistan favoured talks with India to demilitarise Siachen. The two countries have already held 12 rounds of talks over the disputed glacier.

Weather is the biggest foe. Bone-chilling winds whip the landscape and avalanches sweep soldiers into crevasses. The harsh sun burns the skin and, combined with the thin air and sub-zero temperatures, can induce acute depression.

India and Pakistan agreed to a ceasefire over the Siachen glacier in 2003 but thousands of troops are still deployed in the region.

Supplies must be flown in to the Forward Logistics Base by helicopter. India believes that the glacier is of great strategic and diplomatic value.

Many more soldiers have died from the harsh conditions in Siachen than in combat. A war memorial on the bank of the Nubra river is inscribed with the names of all the Indian soldiers who have died on the glacier.

There is a famous local saying: "The land is so barren and the passes so high that only the best of friends and fiercest of enemies come by.''
