Saudi Arabia shuts key oil pipeline after drone attack launched from Iraq

Saudi Arabia has closed a critical oil pipeline after it was attacked by drones launched from Iraq, as conflict in the Middle East widens. Iraq said it had fired a military commander and launched an investigation after admitting the drone attack on its neighbour's East-West pipeline had originated in one of its provinces bordering Iran. The 1,200km (745 mile) pipeline has helped Saudi Arabia - the world's largest crude oil exporter - bypass the Strait of Hormuz. The incident comes amid a major advance by the Iranian-backed Houthi rebels in Yemen, putting more pressure on global oil shipping routes as the US-Iran war stretches into its seventh month.
