Iraq's government has confirmed that attacks on a major Saudi oil pipeline originated from its territory, and it has pledged to conduct a full investigation. The Saudi Foreign Ministry attributed the attacks to several drones launched from Iraq and said the kingdom would not retaliate, giving the Iraqi government time to address the situation. As a precaution, Saudi Arabia shut down the East-West pipeline, a critical artery for oil exports, on Friday. This pipeline is essential for moving oil from the Arabian Gulf to the Red Sea, allowing Saudi Arabia to bypass the Strait of Hormuz, a narrow waterway that has been a frequent target of regional tensions. In response to the attacks, Iraq has closed two key border crossings with Iran—Shalamcheh and Chazabeh—halting all passenger and commercial traffic until further notice. Iran’s state media reported the closures, and a local official, Valiollah Hayati, urged people to avoid the crossings. These border points are important for trade and movement between the two countries, and their closure could further complicate regional logistics and economic ties. Iraq's Prime Minister, Ali al-Zaidi, has ordered an investigation into the operations command in Maysan province and has dismissed its commander after it was determined that attacks on Saudi Arabia were launched from a site in the region. The East-West pipeline plays a vital role in Saudi Arabia's oil exports, with exports through the Red Sea port at the pipeline's end having more than doubled since the Iran-Iraq war disrupted shipping in the Strait of Hormuz, according to the International Energy Agency. Tehran-backed militias in Iraq have been involved in attacks on U.S.-linked targets both inside and outside the country since the U.S. and Israel attacked Iran on February 28. These groups have also coordinated with Yemen’s Houthi rebels to conduct attacks on Saudi Arabia. Meanwhile, concerns are growing that the capture of a key island and a Red Sea port by the Houthi rebels, who are backed by Iran, could disrupt international shipping and increase oil prices. Analysts are worried that the Houthi seizure of Yemen’s port city of Mokha could further complicate shipping in the Red Sea and lead to higher oil prices. Crude oil prices have already risen above $100 a barrel, potentially giving Iran more leverage in any future negotiations.
