Saudi Arabia’s East-West Pipeline Shutdown Amid Escalating Houthi Attacks
By Drooid · · How we work
Core Event
On September 11 the Saudi Ministry of Energy announced the closure of the East-West Crude Oil Pipeline after drone attacks the previous day in the Riyadh and Medina provinces. The 1,200-km line moves up to 5 million barrels per day from the eastern fields to Yanbu, bypassing the Strait of Hormuz. Satellite imagery showed fires at pumping stations along the route.
Background & Context
Built in the 1980s as a Hormuz-bypass, the pipeline became vital after the U.S.–Israel war on Iran began on February 28, limiting Strait traffic. Yemen’s Iran-backed Houthi rebels intensified attacks after announcing a maritime blockade on July 20 and captured Mokha and Perim Island in late August. Their strikes on Saudi energy sites have raised the risk of broader oil-flow disruption.
Timeline
- July 20 – Houthis announce maritime blockade.
- July 28 – Saudi airstrikes target Iraqi militias after drone attacks.
- September 10 – Drone strike damages the pipeline (reported by Iraqi authorities).
- September 11 – Saudi Ministry of Energy declares the pipeline closed.
- September 12 – Iraqi Prime Minister Ali al Zaidi forms a committee to investigate; Sabah al Numan comments on the breach.
- September 15 – Saudi air defenses destroy a Houthi drone near Mecca.
- September 16 (scheduled) – Saudi Arabia offers additional crude via ship-to-ship transfers off Oman’s Sohar port.
Data & Statistics
- Capacity: up to 5 million barrels per day, about 4 % of global supply.
- Saudi crude output: fell below 6 million barrels per day in August (IEA).
- Oil prices: Brent rose above $108/bbl after the attack, later settling near $105-$107.
- Casualties: Over 80 injured in recent Houthi strikes; 13 civilians wounded in attacks on Khamis Mushait, Abha and Taif.
- Humanitarian impact: WHO reported over 500 deaths in Yemen in early August and ?94,000 displaced.
Why It Matters / Impact
The shutdown removes up to 4 % of global oil supply, pressuring prices and inflation. With the line offline, Saudi exports must again rely on the contested Strait of Hormuz, raising geopolitical risk and affecting emerging-market debt costs.
Official Statements & Responses
- U.S. Energy Secretary Chris Wright called the outage a “brief and temporary interruption.”
- Crown Prince Mohammed bin Salman appealed to President Donald Trump and President Abdel-Fattah al-Sisi for assistance; Trump offered intelligence support.
- Prime Minister Ali al Zaidi pledged an investigation and warned militias to disarm by September 30.
- Saudi civil defence lifted air-raid alerts for Mecca, Jeddah, Taif and other cities after missile and drone attacks.
- The U.N. Security Council convened to discuss the Houthi offensive and Red Sea navigation.
On-the-Ground Reports
Residents of Khamis Mushait reported “intense blasts” and sleepless nights after missile strikes (Arab News). Families in Taiz described fleeing with “almost nothing left,” underscoring the humanitarian toll.
Conflicting Reports & Gaps
Reuters attributed the pipeline attack to Iranian-backed militias operating from Iraq, while the Houthis denied involvement and Iran rejected responsibility. Repair-time estimates vary: some experts cite “more than a month,” while others suggest a 3-5-week outage. Saudi officials have not set a definitive resumption date.
What’s Next
- Iraq’s deadline for militia disarmament is September 30.
- Saudi officials indicate plans to restart pipeline flows “within days,” but no concrete date is set.
- Ongoing U.N. Security Council discussions and regional diplomatic talks aim to secure freedom of navigation through the Red Sea and Bab al-Mandeb.
