Saudi Arabia’s Ministry of Energy announced on September 11, 2026, that the East-West Oil Pipeline, also known as the Petroline, was targeted by multiple drone attacks on the morning of September 10. The attacks reportedly caused casualties and led to the precautionary shutdown of the pipeline.
The Saudi Foreign Ministry accused the drones of coming from Iraqi territory, while Iraqi Prime Minister Ali Al-Zaidi condemned the attack and ordered an urgent investigation, stressing that Iraqi airspace would not be used to launch attacks against other countries.
Satellite imagery and NASA fire-monitoring data reportedly showed broad black smoke plumes and abnormal thermal anomalies along the pipeline, particularly in the desert area between Medina and Mahd adh-Dhahab Governorate. Peak fire intensity reportedly reached approximately 70 megawatts, indicating a major oil leak and extensive burning.
What Is This Pipeline?
The East-West Pipeline is a strategic artery approximately 1,200 kilometers long, running from the Abqaiq area in Al-Ahsa in Saudi Arabia’s Eastern Province to the port of Yanbu on the Red Sea coast.
Its maximum designed capacity is approximately 7 million barrels per day, of which around 2 million barrels per day are used to supply refineries in western Saudi Arabia, leaving approximately 5 million barrels per day available for export.
Why Is Striking It So Dangerous?
Since the escalation between the United States and Iran in 2026 disrupted maritime traffic through the Strait of Hormuz, Saudi Arabia has reportedly redirected around 5 million barrels per day of oil exports that previously moved through the Gulf toward this pipeline for shipment from the Red Sea.
The East-West Pipeline therefore became the effective sole outlet for Saudi oil that bypasses Hormuz, making it the strategic “bottleneck” protecting Saudi Arabia’s oil economy from an Iranian closure of the strait.
That is why targeting this pipeline is not simply an attack on an ordinary facility. It represents a direct strike against Riyadh’s last major strategic line of defense for bypassing Hormuz.
Following the incident, Brent crude reportedly rose to $104.61 per barrel, an 8.7% weekly increase. The market reaction reflects the scale of concern over the potential loss of this alternative export capacity.
The Bottom Line
The attack reveals an important reality:
The alternatives Saudi Arabia developed to reduce its exposure to the risks of the Strait of Hormuz, such as the East-West Pipeline, are not inherently immune to attack. Geopolitical risks were not eliminated by pipelines; they were simply shifted from the sea to the land.
