Tehran, April 8 -- Iran's Islamic Revolutionary Guard Corps (IRGC) warned on Tuesday they would deprive the United States and its allies of oil and gas if Washington crossed Tehran's "red lines", a statement carried on state television said. "The Revolutionary Guards once again declare that if the American terrorist army crosses the red lines, our response will go beyond the region," the statement said. It said the Islamic Revolutionary Guard Corps, the ideological arm of Iran's military, would target infrastructure "to deprive the United States and its allies of oil and gas in the region for years". The Islamic Revolutionary Guard Corps also issued a new threat to the Gulf Arab states. "America's regional partners should also know that until today, we have exercised great restraint for the sake of good neighbourliness and have had some reservations in choosing targets for retaliation, but all these reservations have since been removed," it said....
