Israeli Prime Minister Benjamin Netanyahu has told the UN General Assembly that his country will never allow Iran to develop nuclear weapons, even if it has to act alone.
He also described Iran's new leader Hassan Rouhani as a "wolf in sheep's clothing" and dismissed recent moves by the president to try and improve relations with the international community.
