Iran escalated its warning to Washington on Sunday, threatening a regional war if the United States launches military action.
Iranian Supreme Leader Ayatollah Ali Khamenei said that if U.S. forces attack Iran, the fallout would spread across the Middle East, according to the semi-official Tasnim News Agency.
“The Americans should know that if they start a war, this time it will be a regional war,” the 86-year-old leader was quoted as saying.
