Four soldiers and two civilian porters died after they were trapped in an avalanche on the Siachen Glacier's northern sector on Monday, officials said.

According to the officials, eight personnel were trapped in an avalanche at around 3 pm and the Avalanche Rescue Teams from nearby posts were rushed to the location to pull them out.

The rescuers managed to extricate all the eight personnel from under the debris and seven critically injured persons, accompanied by medical teams providing critical care, were evacuated by helicopters to the nearest Military Hospital, where all life saving resuscitative measures were instituted. 

Despite best efforts, six persons -- four soldiers and two civilian porters -- succumbed to extreme hypothermia, officials said.

"The soldiers were part of a patrol. They had been trapped at a height of between 18,000 and 19,000 feet above sea level after they were hit by a snow avalanche," a senior Army officer told IANS.

Expressing his condolences, Home Minister Rajnath Singh tweeted: 

Deeply pained by the demise of soldiers and porters due to avalanche in Siachen. I salute their courage and service to the nation. My heartfelt condolences to their families.

Earlier in February this year, a wall of ice came crashing down at the Siachen Glacier which had trapped 10 Army jawans under 35 feet of snow. 

Battling extreme weather, a team of 150 Army personnel rushed to the site for rescue operations where they found Lance Naik Hanumanthappa Koppad, who was buried under a thick bed of ice at 19,500 feet. However, the sole survivor died three days after being rescued.  

The Siachen is the world's highest battlefield. On a visit to Ladakh last month, Defence Minister Rajnath Singh had announced the reopening of the glacier for tourists.
