India’s missile and bomb strikes on targets in Pakistan and Pakistani-controlled Kashmir have prompted multiple attacks in retaliation between the nuclear-armed neighbors to the point that some are now calling it a de facto war.

India launched multiple Israeli-made Harop drones targeting Pakistan overnight and into Thursday, with one damaging a military site and wounding four soldiers, a Pakistani army spokesman said.

Pakistan accused India of launching air-to-surface missiles that targeted at least three bases. Soon after, Pakistani officials said retaliatory action against Indian bases had begun.
