U.S. President Donald Trump says Iran is probably responsible for an aerial attack on Saudi Arabia that shuts down the kingdom’s East-West oil pipeline. Trump makes the assessment when asked about whether Iran played a role in the incident.

According to reporting that cites Reuters, the attack is launched from Iraq and results in the shutdown of the East-West pipeline, a major crude export route that helps Saudi Arabia send oil while bypassing the Strait of Hormuz. Trump also says he has spoken with Saudi Crown Prince Mohammed bin Salman, describing him as a “good friend.”

Across the outlets provided, the reporting focuses on Trump’s stated judgment and the basic facts of the event—location of launch, target, and the economic/strategic importance of the pipeline. None of the sources here presents an alternative attribution beyond Trump’s “probably” characterization.
