On Saturday, Saudi Arabia halted a major oil link after an unmanned aerial strike fired from Iraq. The shutdown limits oil flow.

Iraq launched an investigation into the strikes and closed three border crossings with Iran.

Yemen retaliated against Houthis. Saudi Arabia has few options as it confronts growing dangers from Iran and its allies. The attack from Iraq caused the shutdown of the pipeline. Iraq's probe into the strikes is ongoing. The closed border crossings with Iran form part of Iraq's response.
