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.

In the days since, tensions have risen dangerously between India and Pakistan, which have fought two of their three wars over Kashmir.

NEW DELHI — A deadly attack on tourists in Indian-controlled Kashmir has again moved India and Pakistan closer to war as the two rivals downgraded diplomatic and trade ties, closed the main border crossing and revoked visas for each other’s nationals.
