DUBAI (Reuters) - Iran's foreign ministry on Thursday summoned the envoys of Britain, France and Germany over what it called a "misuse of the U.N. Security Council to hold a closed-door meeting" over Tehran's nuclear programme, Iranian state media reported.
Britain warned on Wednesday that it would trigger a return of U.N. sanctions on Iran, if needed, to prevent it from getting a nuclear weapon as the Security Council met to discuss Tehran's expansion of its stock of uranium that is close to weapons grade.
