LONDON - The deputy head of Iran’s Revolutionary Guards warned Europe that if it threatens Tehran, the Guards will increase the range of missiles to above 2000 kilometers, the Fars news agency reported on Saturday."If we have kept the range of our missiles to 2000 kilometers, it’s not due to lack of technology. ... We are following a strategic doctrine," Brigadier General Hossein Salami said, according to Fars."So far we have felt that Europe is not a threat, so we did not increase the range of our missiles. But if Europe wants to turn into a threat, we will increase the range of our missiles," he added.
