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.

Following Tuesday's massacre of 26 mostly Indian tourists, hostilities have intensified between India and Pakistan over the hotly contested Kashmir region.

While the case is fairly routine, it comes as India indicates it is preparing to strike Pakistan in response to last week’s deadly terrorist attack.
