Pakistan’s air defense system shot down an Indian drone early Thursday in the eastern city of Lahore, according to Pakistani officials, as India evacuated thousands of people from villages near the two countries' highly militarized frontier in the disputed region of Kashmir.

Pakistan and India accused each other of launching drone attacks, and Islamabad’s Defence Minister said further retaliation was “increasingly certain”, on the second day of major clashes between the nuclear-armed neighbours.

Pakistan said early Saturday that it had struck multiple military targets, days after India launched its largest strikes inside Pakistan in decades.
