On Saturday, Saudi Arabia shut down a key oil pipeline after a drone attack launched from Iraq. The shutdown limits oil flow.

Iraq launched an investigation into the strikes and sealed three frontier posts with Iran.

Yemen retaliated against Houthis. Saudi Arabia faces limited choices as it faces growing dangers from Iran and its allies. The attack from Iraq triggered the shutdown of the pipeline. Iraq's probe into the strikes continues. The closed border crossings with Iran form part of Iraq's response.
