UN nuclear watchdog chief expresses concern over US's anti-Iran rhetoric

The head of the UN nuclear watchdog said Sunday he had no evidence Iran was working actively to build nuclear weapons and expressed concern that escalating rhetoric from the US could bring disaster. "We have information that there may have been some studies about possible [armament]," said Mohamed ElBaradei, who leads the International Atomic Energy Agency. "That's why we have said that we cannot give Iran a pass right now, because there are still a lot of question marks."
