DUBLIN: U.S. President Donald Trump said on Saturday that Iran was probably responsible ‌for an aerial ⁠attack ⁠on Saudi Arabia that shut down its East-West pipeline, one of the kingdom's main routes for exporting crude while bypassing the Strait of Hormuz."I think they are, probably they ​are," Trump told reporters in ⁠Dublin when ‌asked if Iran was ​responsible ​for the attack on the vital ⁠oil conduit.The U.S. president also said ​that he had spoken with ​Saudi Crown Prince Mohammed bin Salman, whom he described as a "good friend."Trump added that Yemen's Iran-aligned Houthis had called his admnistration and indicated they did not ‌want the United States to become directly involved in the conflict."They ​would much ​prefer not ⁠having us involved, and they're letting most ships go through. There's just one country that they're ​not too happy with, and we'll get that straightened out," Trump added.
