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.

The US State Department said it has been in contact with both governments at multiple levels following the April 22 attack on tourists that claimed 26 lives.
