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.

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

As world powers face multiple crises, the one set off by a terror attack in Kashmir is getting scant attention or help in de-escalating between nuclear-armed neighbors.
