Iran’s supreme leader on Monday hit out at the United States a day after new Secretary of State Mike Pompeo visited Riyadh, accusing Washington of trying to stoke a “regional crisis” by provoking its ally Saudi Arabia to confront Tehran. In remarks broadcast on state television, Ayatollah Ali Khamenei reiterated longstanding calls for the United States to “leave” the Middle East, which he called Iran’s home, and said any power seeking to challenge Iran would be defeated.
