Asif said India's rhetoric was intensifying and Pakistan's military had briefed the government on the possibility of an attack.

Pakistan’s army said it shot down an Indian spy drone along their disputed border in the Kashmir region, as tensions rise over last week’s militant attacks that killed 26 people.

Pakistan claims to have shot down an Indian spy drone, according to the state television station. Meanwhile, India is considering closing its airspace to planes from Pakistan. The conflict between the nuclear powers is escalating.

The U.S. State Department said on Sunday Washington was in touch with both India and Pakistan while urging them to work towards what it called a "responsible solution" as tensions have risen between the two Asian nations following a recent Islamist militant attack in Kashmir.
