U.S. official tells CBS News attack on Saudi oil facility was approved by Iran’s supreme leader

President Trump announced on Wednesday that he will issue substantial sanctions against Iran in response to the attacks on a Saudi oil facility last weekend. In Riyadh, Saudi officials presented wreckage from drones that they said proves the attack was “unquestionably sponsored by Iran.” Iran says it wasn’t involved, but CBS News national security correspondent David Martin spoke to a U.S. official who said the attack was approved by Iran’s supreme leader. He joined CBSN with the details. Source
