Armed police and soldiers searched homes and forests for militants in Indian Kashmir on Friday and India's army chief reviewed security there after the killing of 26 men at a tourist site - the worst attack on civilians in nearly two decades.

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.

Relations between India and Pakistan are cratering following a deadly militant attack in Indian-administered Kashmir that has sparked tit-for-tat reprisals and raised fears of another military escalation between the nuclear-armed rivals.
