India and Pakistan have intensified their hostilities over the hotly contested Kashmir region following a massacre of 26 mostly Indian tourists, which New Delhi linked to Pakistan. Pakistan denies it was behind Tuesday's attack by gunmen on a group of tourists in Kashmir.

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 government data shows that when Islamabad closed its airspace in 2019 -- after New Delhi hit it with airstrikes in response to an attack in Kashmir -- domestic airlines saw a financial cost of nearly 5.5 billion rupees ($64.3 million) during the nearly five-month-long shutdown.
