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.

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

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.
