Saudi Arabia has shut down a critical oil pipeline after a drone attack, according to Al Jazeera. The Guardian reports that Riyadh blamed drones launched from Iraq for the strike.
Iraq is investigating the drone strikes on Saudi Arabia and has closed three crossings to Iran, Al Jazeera reports. CNN reports that President Trump said Iran was likely responsible for the attack that shut the vital Saudi oil pipeline.
The incident comes as Saudi Arabia faces mounting threats from Iran and its allies, according to AP News, which reports that the kingdom has few options in response. The pipeline shutdown and the diplomatic fallout — including Iraq's move to close border crossings with Iran — point to rising regional tensions.
What to watch next: whether Iraq's investigation identifies the source of the drones, and how Saudi Arabia responds to the attack.
