India said on Monday it had responded to 'unprovoked' small arms firing from Pakistan along the de facto border for the fourth consecutive night, as it deepens its search for militants in the region following last week's deadly attack on tourists in Kashmir.

India's Daoke village is fenced from Pakistan on three sides and 65-year-old resident Hardev Singh, who has lived through multiple wars between the arch-rivals, knows the drill if another erupts.

Gunfire exchanges between Pakistani and Indian military forces continued for a second day on Saturday across the Kashmir border between the two nations.
