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.

The Indian military on Monday showcased the debris of a likely Chinese-origin PL-15 air-to-air missile, used by Pakistan during recent cross-border engagements, along with remnants of Turkish-origin YIHA and Songar drones shot down by Indian forces.
