Kupwara, Aug 23 (ANI): Fierce gun battle is going on between Indian army and militants in Kupwara district of Jammu and Kashmir on Saturday. Acting on an intelligence input, soldiers launched a search operation in Gugerpati area to nab ultras on Friday evening. The extremists hiding in the area opened fire at soldiers, leading to exchange of fire.
