Diplomats have walked out of a speech by the Iranian president at a UN anti-racism conference after he described Israel as a “racist government”. Two protesters, wearing coloured wigs, disrupted the beginning of the speech by President Mahmoud Ahmadinejad – followed by the Western walkout. Others enthusiastically clapped as Mr Ahmadinejad continued his address. France said it was a “hate speech”. A number of other Western countries have boycotted the conference altogether.
