UN chief Ban Ki-moon today asked Iran to build "international confidence" in its nuclear programme by fully complying with the global obligations under NPT and cooperating with IAEA, shortly after Tehran slammed the UNSC for being "unjust and completely undemocratic".

Addressing the leaders and delegates gathered in Tehran for the 16th NAM Summit, Ban also urged the sanctions-hit country to engage constructively in P5 plus 1 (US, UK, Russia, France and China plus Germany) talks while pursuing its nuclear programme. The UN chief also said Tehran, during its chairmanship of the 120-nation Non-Aligned Movement, could demonstrate that it can play a moderate and constructive role. 

Ban also stressed that all leaders should ensure that the world should be free of nuclear weapons and work together to check illicit arms trade.
