Strait of Hormuz: Saudi Arabia Shuts Down Critical East-West Pipeline After Drone Strikes Launched From Iraq
The geopolitical struggle in the Persian Gulf has escalated to a critical energy-security crisis. On September 11, 2026, Saudi Arabia shut down its 1,200 km (746-mile) East-West Crude Oil Pipeline (Petroline) following multiple drone strikes. This shutdown removes Saudi Arabia's primary alternative route for exporting crude oil, leaving its exports severely strangled while the Strait of Hormuz remains effectively closed by Iran and the Bab el-Mandeb Strait falls under Houthi control (see Saudi Front: Dammam Airport and Shaybah Dead — US Pulls Diplomats, Britain Sends Typhoons).
The Aerial Attacks on Pumping Stations
On the morning of Thursday, September 10, 2026, a series of drone attacks struck the East-West pipeline in the Riyadh and Medina (Madinah) regions of Saudi Arabia, triggering fires and causing structural damage to pumping facilities, as well as injuring several people.
Both Riyadh and Baghdad confirmed that the drones had been launched from Iraqi territory, where Iranian-backed militias operate. Following the attacks, Saudi Arabia's Ministry of Energy announced on Friday, September 11, that the pipeline had been shut down "as a precautionary measure" while technical teams secured the site and assessed the safety of the infrastructure.
Iraqi Prime Minister Ali Al Zaidi ordered an immediate investigation into the drone launches from Iraq and issued a statement declaring Baghdad's "rejection of any aggression that threatens the Kingdom's security and stability." Riyadh stated that it reserved the right to take all necessary measures to protect its sovereignty and critical facilities, but would not immediately retaliate following a request from Iraq's Prime Minister.
Squeezing Global Energy Buffers
The closure of the East-West pipeline is an extremely severe blow to global energy security:
- Alternative Route Blocked: Early in the US-Iran conflict, Saudi Arabia relied on the East-West pipeline to shift its crude oil exports away from the Persian Gulf to the port of Yanbu on the Red Sea, bypassing the closed Strait of Hormuz1.
- Massive Capacity Removed: The pipeline has been moving 4 to 5 million barrels of oil per day (bpd) in recent months, representing roughly 4% to 5% of the global oil supply.
- Price Surge: With its primary bypass route closed, Saudi Arabia's export capabilities are critically restricted. This restriction, combined with the Houthi capture of the Bab el-Mandeb Strait (see Saudi Front: Dammam Airport and Shaybah Dead — US Pulls Diplomats, Britain Sends Typhoons), has sent Brent crude oil prices surging past $107–$108 a barrel.
Energy analysts warn that the key buffers that protected the global energy market over the last six months have now been completely worn away, leaving global markets highly vulnerable to further supply shocks.
