Tehran, Sept 20 (UNI) Iranian President Hassan Rouhani has used a speech to the UN General Assembly to hit back at Donald Trump over the US president's criticisms of his country and its 2015 nuclear deal, a BBC report said today. In his debut speech to the UN on Tuesday, President Trump included Iran among a "small group of rogue regimes". He described the nuclear deal as an "embarrassment" to the United States. Mr Rouhani responded by describing Mr Trump as a "rogue newcomer to international politics". He denied his country would be the first to violate the agreement but said Iran would "respond decisively and resolutely to its violation by any party." It would be a "great pity", he added, if the agreement were to be destroyed by Mr Trump. UNI XC SNU 2228
