MOSCOW (Reuters) - Russia's deputy foreign minister Sergei Ryabkov said on Monday it would be too risky for the United States to try to reopen a nuclear deal with Iran, the Interfax news agency reported. "Don't try to fix what is not broken," Ryabkov was quoted as saying in an interview with the agency. (Reporting by Denis Pinchuk; Writing by Maria Tsvetkova; Editing by Andrew Osborn)
