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.

Tensions have escalated between the two nuclear powers following Tuesday’s attack on tourists in Indian Kashmir.

Following the attack on tourists in Kashmir, the two neighbors are accusing each other and threatening retaliation. They have suspended two major bilateral treaties.
