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.

Indian and Pakistani troops exchanged gunfire for a second straight day on Saturday as ties plummeted between the two nuclear-armed neighbours after an attack on tourists blamed on Pakistani militants killed 26 in India's Kashmir region.

India said its troops responded to firing from Pakistan military positions in the Jammu and Kashmir region for a second day on Saturday, as tensions remained escalated between the neighbors after a deadly attack on tourists this week.
