Iran said on Sunday the threat of sanctions was a "psychological game" aimed at putting pressure on the Islamic Republic over its nuclear programme. "I think the issue of sanctions is more like a psychological game," Foreign Ministry spokesman Hamid Reza Asefi told a news conference. "Right now we should think about solving the issues through negotiations. I think the matter of sanctions was only brought up by some Zionist American circles to exert pressure," he was quoted as saying by Reuters.
