Regret the Error

An article “Israel list names Russians helping Iran build nuclear bomb” (World News, last week) stated that Robert Einhorn, the special adviser for non-proliferation and arms control to Hillary Clinton, was understood to believe that Russian companies have also supplied material that has been used by Iran in the production of ballistic missiles. Mr Einhorn assures us that he does not recall having said anything like that to anyone and was not given an opportunity to refute the statement. We regret the error and are happy to set the record straight.
