Saudi Arabia said drones launched from Iraq hit its East-West pipeline in the Riyadh and Medina regions on Thursday morning local time, causing human injuries and damage. The foreign ministry said the kingdom had decided, following a call from Iraqi Prime Minister Ali al-Zaidi, "to support the efforts of the Iraqi government … to prevent attacks launched from Iraq against the Kingdom and neighbouring countries." It added that Saudi Arabia reserves the right to take all necessary measures to protect its sovereignty and facilities.
The 1,200-kilometre (745-mile) pipeline, which links Abqaiq near the Gulf to the Red Sea port of Yanbu, has become critical since the start of the US-Iran war, allowing Saudi Arabia to bypass the Strait of Hormuz after Iran closed it. By early June, Saudi Arabia had more than doubled oil exports from Yanbu to more than 5 million barrels per day, according to the International Energy Agency. The pipeline has been moving 4 to 5 percent of global oil supply, according to Reuters.
Iraq condemned the assault and removed the operations commander in Maysan province, which borders Iran, after investigations confirmed the drone attacks originated from there. The attack comes as Iran-backed Houthi rebels made their biggest territorial gains in years, capturing Mayun (also known as Perim), a barren volcanic island inside the Bab el-Mandeb Strait. The seizure was confirmed by a senior military official with Yemen's internationally recognised government and by a Houthi official, both speaking anonymously. Yemen's Saudi-backed government forces said they had struck Houthi fighters in the coastal city of Mokha.
Regional officials told the Associated Press that the Houthis helped Iraqi militias plan and execute the attacks. Saudi Arabia and the US bombed Iranian-backed militias in Iraq in July after similar drone attacks on Saudi oil facilities were claimed by the Houthis.
