Recovered missile circuit boards are of particularly high interest, as they could reveal whether the attack originated from Iran, which the Trump administration has singled out.

The Times did its own analysis of publicly available evidence to determine what might have transpired. One thing is certain: The attack exceeded anything that Houthi rebels in Yemen, who claimed them, have done before.

Recovery: Saudi Arabia’s newly named energy minister, Prince Abdulaziz bin Salman, said that 50 percent of the oil production cut by the strikes had been restored.

Go deeper: If Iran did play a role in the attack, it would not be a surprise. Iranian scholars say that Tehran has concluded that its recent aggressions have strengthened its leverage with the West and in the region, and judge that President Trump is reluctant to risk a military confrontation.
