A day after the U.N. appealed for restraint following Tuesday's deadly attack in Indian-administered Kashmir, India reported an exchange of fire across the de facto border in the disputed region.

Pakistan called India's actions “irresponsible" and canceled visas for Indian nationals, suspended all trade with India and closed its airspace to Indian aircraft.

The Indian Army said its troops responded to 'unprovoked' small arms fire from multiple Pakistan Army posts that started around midnight on Friday.
