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

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.

Indian Prime Minister Narendra Modi has vowed to pursue the attackers to "the ends of the earth" and said that those who planned and carried it out "will be punished beyond their imagination". Calls have also grown from Indian politicians and others for military retaliation against Pakistan.
