Saudi Arabia shut its East-West oil pipeline as a precaution after drone attacks that Riyadh said originated in Iraq, while Iraqi authorities dismissed Maysan province’s operations commander and opened an investigation. Iraq also closed the Shalamcheh and Chazabeh crossings with Iran to passenger and commercial traffic until further notice. The pipeline has become critical to Saudi exports since the Iran war disrupted tanker shipping through the Strait of Hormuz, with International Energy Agency data showing Red Sea exports from its terminus more than doubled. U.S. President Donald Trump said Iran was probably behind the attack and said his administration had held discussions with Yemen’s Houthis, whose seizure of Mokha has intensified concerns over Red Sea shipping and oil prices.
