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

Pakistan's defence minister said on Monday that a military incursion by neighbouring India was imminent in the aftermath of a deadly militant attack on tourists in Kashmir last week, as tensions rise between the two nuclear-armed nations.

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.
