U.S. President Donald Trump said Iran was probably responsible for an aerial attack that shut Saudi Arabia’s East-West pipeline, a major crude-export route designed to bypass the Strait of Hormuz. Trump said he had spoken with Saudi Crown Prince Mohammed bin Salman, whom he called a good friend. He also said Yemen’s Iran-aligned Houthis had contacted his administration and indicated they did not want direct U.S. involvement, while allowing most ships to pass through, apart from one country with which they remained unhappy.
