Tehran, June 20 (Xinhua) -- Only Iran's former Revolutionary Guards Chief Mohsen Rezaei attended a special meeting of the Guardians Council with presidential candidates on Saturday, the official IRNA news agency reported.

    Iran's former Prime Minister Mir-Hossein Mousavi and former Parliament Speaker Mehdi Karroubi failed to attend the meeting, IRNA said.

    According to local IRNA news agency, Mousavi and Karroubi who had also been invited to this meeting, were absent without giving any reason.

    "But the council is still ready to receive them," IRNA said.

    The Spokesman of the Guardian Council Abbas-Ali Kadkhodaei said on Wednesday that candidates of Iran's recent presidential election were invited to its upcoming meeting session which is to be held within the next few days.

    Iran's Supreme Leader Ayatollah Seyyed Ali Khamenei has ordered Iran's Guardian Council, the top legislative body, to investigate the claims of "fraud" in the recent presidential election.
