India fired attack drones into Pakistan on Thursday, wounding four soldiers, the Pakistani military said. India, meanwhile, accused its neighbor of attempting its own attack, as tensions soared between the nuclear-armed rivals.

India fired missiles into Pakistani-controlled territory in several locations early Wednesday, killing at least 19 people including a child, in what Pakistan’s leader called an act of war. India said it struck infrastructure used by militants linked to last month’s massacre of tourists in the Indian-controlled portion of Kashmir.

The Indian armed forces launched "Operation Sindoor," hitting nine sites in Pakistan and Pakistan-occupied Jammu and Kashmir, the government said in a statement on Wednesday. No Pakistani military facilities have been targeted,
