The sources reported that the Pakistan army has started a rescue operation in the area with the help of locals. Heavy machinery has also been sent to speed up the rescue operation.
However, the army has still not confirmed any casualties.
In January last year, another four soldiers were killed by an avalanche while in the previous year another four died when their vehicle was buried under an avalanche near Leh, the main city in the high-altitude region known as Ladakh.
Avalanches and landslides are common at the Siachen Glacier during the winter and temperatures there can drop as low as minus 60 degrees Celsius.
An estimated 8,000 troops have died on the glacier since 1984, almost all of them from avalanches, landslides, frostbite, altitude sickness or heart failure rather than combat.
