U.S. President Donald Trump said Iran was probably responsible for an aerial attack on Saudi Arabia that shut down the kingdom’s East-West pipeline, a major crude export route that bypasses 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 the United States to become directly involved in the conflict, while allowing most ships to pass through and objecting to one country.
