Teheran's ban on nuclear arms and IAEA's efforts have created right atmosphere for P5+1 to resume negotiations with Iran

Talks between the International Atomic Energy Agency and Iran concluded on Thursday in Teheran without reaching a much-hoped-for deal. But the two sides have agreed to meet again on Feb 12.

On the eve of IAEA experts' arrival, Iranian Foreign Ministry spokesman Ramin Mehmanparast said on Tuesday that a religious decree, issued earlier by Iran's supreme leader Ayatollah Ali Khamenei, on nuclear weapons ban is binding on the Islamic republic. He also said Iran is ready to register it as an "international document".
