IS 'wants to destroy civilisation'
Iran's president says the goal of extremists such as Islamic State who are creating chaos in the Middle East is the destruction of civilisation and the rise of Islamophobia.
Hassan Rouhani told the UN General Assembly that would create "a fertile ground for further intervention of foreign forces in our region".
He said the extremists come to the Middle East from around the world with a single ideology - "violence and extremism".
Mr Rouhani doubted the world was united against the threat posed by the extremists, saying all countries that supported them must apologise, not only to the "past generation but to the next generation".
In a wide-ranging speech, Mr Rouhani also said an agreement on Iran's nuclear programme is possible before a November deadline if the West wants a deal and shows flexibility.
He said Tehran is determined to continue its confidence-building approach and transparency in the negotiations.
Mr Rouhani added that an agreement would create a new environment "for co-operation at regional and international levels, allowing for greater focus on some very important regional issues such as combating violence and extremism in the region".
He said it would also be "a historic opportunity" for the West to show it does not ignore an international treaty that allows Iran to have a peaceful nuclear programme to produce energy.
