No group has yet claimed responsibility for the attack so far. The Army has no information whether these men were local militants or infiltrators across the India-Pakistan Line of Control.
The region of Kashmir has been disputed by India and Pakistan since the dissolution of British India and the establishment of the two states in 1947. Some local residents, most of them Muslims, especially those residing in the Kashmir Valley, call for greater autonomy or even independence from India.
