According to the Indian Army, a contingent of about 40 army personnel from the High Altitude Warfare School (HAWS) and the Army Adventure Wing of the Indian Army were involved in routine training activities near Mount Kun (Ladakh) on Sunday.
During the group's training ascent, it faced an unexpected avalanche.
"Four of our dedicated personnel were trapped underneath. The mortal remains of one person struck by the avalanche have been recovered," an army official told the media.
Amid inclement weather and heavy snow pile-up, search and rescue operations continue to locate and recover others trapped under the massive snow deposit, the official said.
