Saudi Arabia Shuts East-West Pipeline After Iraqi Drone Attack Amid Widening Red Sea Conflict
The geopolitical and energy-security crisis in the Persian Gulf has escalated to an unprecedented level following a devastating, coordinated drone attack on Saudi Arabia’s vital East-West Crude Oil Pipeline (Petroline). On September 10–11, 2026, multiple drones targeted pipeline pumping stations in the Riyadh and Medina regions1, causing massive fires, significant structural damage, and multiple injuries2. On September 11, 2026, the Saudi Ministry of Energy shut down the entire 1,200 km (750-mile) pipeline as a precautionary measure. Industry and diplomatic sources report that the pipeline suffered severe damage at multiple locations and will remain out of commission for weeks as repairs are carried out. This shutdown has sent global oil prices soaring, with Brent Crude climbing to $107 per barrel and WTI rising above $103.
The attack represents a catastrophic blow to Saudi Arabia's energy export infrastructure. With the Strait of Hormuz effectively closed by Iran amid the ongoing 2026 U.S.-Iran War, the East-West pipeline was the kingdom’s primary alternative route to export its oil, carrying 4 to 5 million barrels per day (about 4% to 5% of global supply) to the Red Sea port of Yanbu. The loss of this conduit severely restricts Saudi Arabia's export capabilities. Both Riyadh and Baghdad confirmed that the drone strikes originated from Iraqi territory, specifically Maysan Governorate in southern Iraq, where Iran-aligned Popular Mobilization Forces (PMF) operate. In a swift response, Iraq's Prime Minister Ali al-Zaidi chaired a National Security Council meeting, dismissed the military commander and police chief of Maysan province, and shut down the main border crossing with Iran there. U.S. President Donald Trump publicly blamed Iran for the attack, stating they were "probably" behind it.
The pipeline shutdown coincides with a major Houthi offensive along Yemen's Red Sea coast. Supported by direct guidance from Iran's Revolutionary Guards, Houthi forces have seized the strategic island of Mayun in the Bab el-Mandeb strait and captured key coastal cities like Mokha, effectively tightening their maritime blockade on Saudi shipping. On Monday, September 14, 2026, the Houthis launched a massive wave of ballistic missiles and drones targeting three Saudi cities—Khamis Mushait, Abha, and Taif—injuring 13 civilians. Saudi Arabia has warned that it will react "firmly" to these attacks, raising the immediate threat of direct military retaliation inside Iraq or against Iranian targets.
