(CNN) Indian authorities have released footage showing the final moments of the climbers who died in the Indian Himalayas in May.

The video was found on a "memory video device" near the Nanda Devi East, the Indo-Tibetan Border Police (ITBP) said Monday, which showed the group of climbers moving slowly near the summit on the unnamed peak.
