Pakistan called India's attacks an "unprovoked and blatant act of war" in a statement on Wednesday morning.
"The Indian Air Force, while remaining within Indian airspace, violated Pakistan's sovereignty by using heavy weapons, targeting civilian populations across the International Border in Muridke and Bahawalpur, and across the Line of Control in Kotli and Muzaffarabad," a statement from Pakistan's foreign ministry said.
"India's act of aggression has resulted in the martyrdom of civilians, including women and children. This act of aggression has also posed a grave threat to commercial air traffic."
India early Wednesday said it launched a military operation against Pakistan, hitting "terrorist infrastructure" in both Pakistan and Pakistani-administered Kashmir, in a major escalation between the two neighbors.
The attacks come more than two weeks after a massacre of tourists in Indian-administered Kashmir, which New Delhi blamed on its neighbor - a claim Islamabad denies.
