Chief of Air Staff Air Chief Marshal Sohail Aman on Thursday said Pakistan's armed forces were not worried about India at all.

Speaking at the 9th International Defence Exhibition and Seminar (IDEAS) a day after three Pakistan Army men were killed exchanging fire with Indian troops across the Line of Control (LoC), the chief of air staff said, "We are not worried about India at all, it is better if they show some restraint."

Aman called on India to resolve the Kashmir issue, saying: "They should speak on matters of principle and our ties will improve."

The air chief's statement comes a day after Pakistan and India exchanged threats as tensions between the two neighbours flared in the aftermath of deadly clashes on the LoC. The clashes left 13 people, including three troops dead on the Pakistani side.

Also on Wednesday, Indian troops shelled civilian populations almost all along the LoC in Azad Jammu and Kashmir after a daylong lull and hit a passenger bus, leaving 10 civilians dead and 21 others injured.

These were the heaviest civilian killings in a single day over the past 13 years since India and Pakistan signed a ceasefire agreement in November 2003.
