On Saturday, Saudi Arabia shut down a key oil pipeline after an unmanned aerial strike launched from Iraq. The shutdown limits oil flow.

Iraq launched a probe into the strikes and closed three frontier posts with Iran.

Yemen hit back against Houthis. Saudi Arabia is running out of options as it faces mounting threats from Iran and its supporters. The attack from Iraq triggered the pipeline shutdown. Iraq's probe over the attacks continues. The closed frontier posts with Iran are part of Iraq's response.
