Multiple explosions were heard in different parts of Pakistan and Pakistani Kashmir.
Lt Gen. Ahmed Sharif Chaudhry, the spokesman of Pakistan's military, told local broadcaster Geo News that India had fired missiles on the cities of Bahawalpur, Muridke, Bagh, Muzaffarabad and Kotli from its own air space. He confirmed at least three deaths and more than a dozen injuries.
He said Pakistani forces had begun retaliatory attacks against India.
The escalation between the nuclear-armed neighbors comes in the wake of April 22 attack in Pahalgam, Indian-administered Kashmir in which 26 people were killed. India had blamed Pakistan for the attack, claiming there were cross-border links.
Pakistan denied that it had anything to do with the killings.
