Saudi Arabia shut its 1,200 km East-West crude pipeline from Abqaiq to Yanbu on Friday September 11 2026 after drone strikes launched from Iraq's Maysan province hit the line in the Riyadh and Medina regions on September 10-11, causing fires; no group claimed responsibility and analysts suspect Iran-aligned Iraqi groups. The line carries 4 to 5 million barrels a day, roughly 4 to 5% of world supply, and had been the kingdom's main bypass around the closed Strait of Hormuz. The Energy Ministry called the shutdown a precaution while teams assess safety; the April strike on a pumping station was restored within three days, but the extent of this damage is undisclosed. Brent jumped toward $110 before settling near $105 that afternoon.
