The price of oil is now closer to $90 (£67) a barrel after it hit almost $120 (£89) on Monday. It comes after Trump told reporters the war with Iran was "very complete, pretty much". However, he later appeared to walk back somewhat, saying "we're going to go further". Despite the fall in prices, Brent crude is still $20 higher than it was before the conflict began. And the pressure on prices looks set to continue, with Iran saying that it will not allow "one litre" to be exported while attacks continue, according to Reuters. Rising costs and mixed messaging from the president mean the conflict is fraught with political risk for Trump, writes North America correspondent Anthony Zurcher.
