British delegates walked out of a speech by Iranian President Mahmoud Ahmedinejad at the United Nations, in which he attacked the US and Israel’s nuclear programmes at a session on nuclear proliferation.

The US Department of Defence used the same meeting to call for transparency about nuclear arms – revealing it has 5,113 nuclear weapons currently in its arsenal.

Iran’s President Mahmoud Ahmadinejad has said the US must choose between supporting Israel or Iran if any real change of policy is to take place.

Mr Ahmadinejad said it was time for US President Barack Obama to live up to his slogan: “Change”.

Claims have resurfaced about Iranian President Mahmoud Ahmadinejad’s possible Jewish heritage.

A close-up of Mr Ahmadinejad holding up his identity card has been released, showing that the Iranian President’s previous name was Saburjian.

British, American and French diplomats led a walkout at the United Nations general assembly during a virulently anti-Jewish and anti-Israel speech by Iranian President Mahmoud Ahmadinejad.

Mr Ahmadinejad infuriated many delegates with claims of a 'Jewish conspiracy'.

Iranian President Mahmoud Ahmadinejad has told Iranians that the Holocaust is a "lie", and that confronting Israel was an Iranian's "national and religious duty".

Speaking at the anti-Israel Quds Day rally at Tehran University, Mr Ahmadinejad said: "The Holocaust is a pretext for the creation of the Zionist regime and is false. It is a lie based on an unprovable and mythical claim. “

The nomination of General Ahmad Vahidi as Iranian Defence Minister has shocked the international community.

General Vahidi is wanted by Interpol for his alleged role in the 1994 bombing of the AMIA Jewish community centre in Argentina.

Many see his nomination as yet another sign that Mahmoud Ahmadinejad is still intent on antagonising the West, and Israel especially.

Iranian President Mahmoud Ahmadinejad will attend the United Nations anti-racism conference in Geneva next week.

The news increased Jewish concerns about the conference, which is a follow up to the 2001 conference held in Durban dominated by heated rows over the Middle East.

He wants Israel to disappear; he has questioned the Holocaust; he believes Zionists pull the financial strings in the world. Many Jews would probably rate him public enemy number one. But could President Mahmoud Ahmadinejad be hiding a secret?
