Saudi Arabia shut its 1,200km East-West oil pipeline after Iraq acknowledged that drones launched from the Maysan governorate attacked the facility. The pipeline helps the world’s largest crude oil exporter bypass the Strait of Hormuz and has been carrying an estimated 4% to 5% of global oil supply, Reuters reported, citing ship tracking companies and analysts. Saudi Arabia said the attack caused injuries and damage that remained under assessment, but it would not retaliate at this stage after a call from Iraq’s prime minister. Iraq removed the operations commander in Maysan and opened an investigation. The incident came as Iranian-backed Houthi rebels advanced in Yemen, claiming control of the Bab al-Mandab Strait and saying maritime navigation was safe for all companies except Saudi vessels. The developments have tightened pressure on both sides of the Arabian Peninsula and pushed crude oil above $100 a barrel for the first time since July, amid a US-Iran war entering its seventh month.
