India said on Monday it had responded to 'unprovoked' 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 and Pakistan have exchanged gunfire for a fourth night in a row in the wake of a deadly attack on tourists in Indian-administered Kashmir last week.

India has yet to present clear evidence of who conducted the attack on April 22nd that killed 26 mostly Hindu men in Pahalgam, a popular tourist spot in the Muslim-majority region. But local police are searching for two Pakistani suspects and one Indian.
