Iran denies involvement in Saturday's air attacks, which were claimed by Iran-aligned Houthi rebels in Yemen. But unnamed US officials speaking to US and international media say the direction and extent of the attacks cast doubt on Houthi involvement. Following a briefing from his military and intelligence advisers at the White House on Monday, Trump was asked whether Iran was to blame for the attack. He said: “Well, it’s looking that way.
“That’s being checked out right now.”
He said that while he did not want war with Iran, the US was “more prepared” for a military conflict than at any point in its history.
Mr Trump added: “With all that being said, we’d certainly like to avoid it.”
The Houthis have launched attacks on Saudi soil before, including on oil pipelines.

But this attack was on a much bigger scale, hitting the world's biggest oil-processing plant and another oil field.
The attacks targeted Abqaiq, the site of the world's largest oil processing plant, run by the Saudi state oil company, Aramco, and the Khurais oilfield.
Khurais is the closest of the targets to the Yemen border, but is still a considerable 770km (480 miles) away.
US officials said there were 19 points of impact on the targets, which could have come from a mix of drones and cruise missiles.
