IRNA - Spokesman for Foreign Ministry says Iran believes that a team which is near to failure changes its players, meanwhile, Tehran does not care the consecutive changes of the US failed executives.

Abbas Mousavi made the remarks at his weekly press conference while commenting on resignation of the US Special Representative for Iran Brian Hook.

The spokesman cited to the US attempt to extend arms embargo on Iran, and said the embargo is more a threat against the UN Security Council's legal mechanism than a threat to Iran.

He further cautioned the UNSC against the US plot because Washington aims to destroy the United Nations Security Council.
