India and Pakistan engaged in the most intense fighting in decades with four days of escalating conflict that included fighter jets, missiles and drones packed with explosives. It ended almost as abruptly as it began.

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.
