Abqaiq-Khurais attack (September 2019)
Drones and cruise missiles struck Saudi Aramco's Abqaiq and Khurais oil facilities, temporarily halving Saudi oil production. The attack showed that Saudi Arabia's most critical infrastructure was vulnerable to precision strikes.
Saudi oil production was cut by about 5.7 million barrels per day, roughly half of output. Oil prices spiked before recovering.
The attack demonstrated that Iran-backed forces could strike deep inside Saudi Arabia, a vulnerability that persists today.
Like the airport attacks, the 2019 strike showed that Houthi or Iranian forces can hit Saudi civilian infrastructure despite air defenses.
