President Trump said Monday that Iran appeared to have been responsible for the weekend attack on Saudi Arabian oil facilities. But he also said he would “like to avoid” a military conflict with Tehran, emphasized his interest in diplomacy and played down the attack’s jolt to the global oil market.
Asked at the White House whether Iran was behind the strikes on Saturday that crippled much of Saudi Arabia’s oil output, Mr. Trump said, “It’s looking that way.” But he stopped short of a definitive confirmation, adding, “That’s being checked out right now.”
The attack was the most destructive blow to Saudi Arabia since it began waging war in Yemen more than four years ago. The damage inside Saudi Arabia helped drive world oil prices up by 10 percent on Monday, the fastest rise in more than a decade.
Mr. Trump’s comments represented a notable shift in tone from the day before, when he wrote on Twitter that the United States was “locked and loaded,” ready to take action based on Saudi Arabia’s needs.
On Monday, he told reporters he had not “promised” to protect the Saudis. Rather, Mr. Trump said, he will “sit down with the Saudis and work something out.”
The comments from Mr. Trump and the Saudis suggested they did not want the episode to escalate into a wider conflict, just a week before world leaders converge at the United Nations for the General Assembly. Mr. Trump had proposed meeting with Iran’s president, Hassan Rouhani, possibly at the annual gathering in New York, although Iran ruled that out on Monday.
The Houthis insisted on Monday that they had carried out the strikes using drones, and threatened more. They made no reference to whether Iranian equipment or training had played a role.
The Houthis can strike at will anywhere in Saudi Arabia, he said, and their actions against it “will expand and be more painful.”
United Nations experts say that Iran has supplied the Houthis with drones and missiles that have greatly expanded their offensive capacity.
Iran’s Islamic Revolutionary Guards Corps has worked extensively with other allied groups in the region, including Hezbollah in Lebanon and Syria, Hamas in Gaza, and Shiite militias in Iraq.
The attack forced the shutdown of facilities at Abqaiq and Khurais, which ordinarily are responsible for most of the crude oil produced by Saudi Arabia; the kingdom supplies about a tenth of the worldwide total.
In May and June, several tankers were damaged in or near the Strait of Hormuz, in what American officials said were Iranian attacks. Iran has also seized several foreign ships.
