What happened

Drones and cruise missiles struck Saudi Aramco's Abqaiq crude-oil processing facility, the world's largest, and the nearby Khurais oil field before dawn, igniting large fires that were brought under control within hours. The strikes temporarily knocked out about 5.7 million barrels per day of production, more than half of Saudi Arabia's output and roughly 5% of global supply at the time, and caused the largest single disruption to global oil supply in decades. Brent crude jumped as much as 20% in the following trading session before easing. Aramco restored most production within about three weeks, drawing on stored inventory in the interim. Yemen's Houthi movement claimed responsibility, but Saudi and US officials said the attack profile pointed to Iran rather than Yemen; Iran denied any role.
