Pakistan on Tuesday accused Indian jets of briefly violating its airspace, days after India said one of its soldiers had been killed by Pakistani troops.
The Pakistan Air Force said it scrambled two fighter jets after two "high-speed" Indian planes crossed the border over its eastern province of Punjab at about 10:40am (05:40am GMT).
It said they left Pakistani airspace two minutes later.
India accused Pakistan last week of fomenting militancy in the Indian state of Punjab and killing a soldier in cross-border firing. Pakistan rejected both allegations.
The nuclear-armed states have fought three wars, two of them over Kashmir.
Pakistani Prime Minister Nawaz Sharif took office last week, promising to pursue good relations with India and resolve outstanding disputes such as Kashmir.
