The new president of Egypt Mohamed Morsi says a vicious campaign around the world against what Muslims hold sacred is unacceptable. In his maiden speech to the United Nations General Assembly, the first by a democratically chosen Egyptian president, Mr Morsi called for an end to double standards. He said all religious and cultural views must be respected and the UN had to address the phenomenon of Islam phobia. James Robbins was at the UN.

President Morsi said Muslims had become victims of vicious and unacceptable campaigns against what they held sacred. He said the insults hit on the prophet Muhammad was obscene and part of an Islam phobia which required action by the United Nations. President Morsi said that Egypt respected freedom of expression, but not freedom of expression used to incite hatred against anyone. But he said Egypt also stood firmly against the use of violence in response.

The president of Iran Mahmoud Ahmadinejad has accused the west of nuclear intimidation in what is expected to be his last address to the UN General Assembly. He was speaking a day after president Obama said America would do what it had to in order to prevent Iran obtaining a nuclear weapon. James Reynolds reports.

Iran's president appears to enjoy taking center stage, then holding on to it for as long as he can. In his 34-minutes speech, Mr. Ahmadinejad touched on many his preferred topics, the historic evils of imperialism, the failings of the current world order and the dangers posed by Israel. Mahmoud Ahmadinejad's worldview extends beyond severe criticisms of the west to include religious and even mythical beliefs. He ended his speech by talking about his hopes for the arrival of the al-Mahdi, a redeemer revered by believers of Shia Islam.
