The world's first drone war between nuclear-armed neighbours has erupted in South Asia. On Thursday, India accused Pakistan of launching waves of drones and missiles at three military bases in Indian territory and Indian-administered Kashmir - an allegation Islamabad swiftly denied.

India’s missile and bomb strikes on targets in Pakistan and Pakistani-controlled Kashmir have spiked tensions between the two nuclear-armed neighbors, with Pakistan’s leader calling the attacks an act of war.

India launched multiple Israeli-made Harop drones targeting Pakistan overnight and into Thursday, wounding at least four soldiers, Pakistan army officials said.
