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.

SRINAGAR (Reuters) -India's army chief will review security arrangements on Friday and visit the site of a deadly attack on tourists in Indian Kashmir earlier this week, with fears of fresh tensions with long-time rival and neighbour Pakistan spooking markets.

Relations between India and Pakistan are cratering following a deadly attack in the disputed Himalayan region of Jammu and Kashmir that left more than two dozen tourists dead.
