The officials said Tuesday that Pakistani adviser Nasser Khan Janjua spoke with India's security adviser Ajit Doval by phone briefly on Monday, discussing ways to restore calm.

It's the first such contact amid tensions that have been running high between the two nuclear arch-rivals since India claimed a militant attack in its part of Kashmir had killed 19 soldiers on September 18.

The three officials, including a close aide of Prime Minister Nawaz Sharif, spoke on condition of anonymity because they were not authorised to disclose the information to the media.

Monday's five-hour gunfire exchange caused no casualties.
