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.

While Pakistan was attempting, and failing, to strike military installations in India using missiles and drones for the second day running, the Indian armed forces launched drones at four sites in the country and destroyed an air defence radar.

Pakistan’s army spokesman, Lt. Gen. Ahmad Sharif, said an Indian drone attacked a military target near Lahore overnight, wounding four soldiers, while the country’s air defense system intercepted and shot down 12 Indian drones that entered Pakistani airspace at various locations.
