Iran criticized what it described Sunday as the double standard in US nuclear policy, citing Washington recent deal with India as an example. Foreign Ministry spokesman Hamid Reza Asefi also said Washington was systematically trying to show Tehran in a bad light. "The United States' approach is a form of double standards. It signed a contract with a country that was not a member of the Nuclear Nonproliferation Treaty. That is objectionable. On the other hand, it approaches Iran in such a (bad) way," Asefi told a news briefing.
