While clearly criticising Mr Trump and the United States, Mr Rouhani often declined to mention the President by name, telling the audience it would be a "great pity" if the nuclear agreement were "destroyed by rogue newcomers to the world of politics".
"We do need the support, I think, of our allies - the European allies and others - to make the case as well to Iran that this deal really has to be revisited", Tillerson said in an interview to Fox News. Rouhani claimed that Israel is "daringly preaching" against the nuclear deal with Iran while it threatens the security in the region with its nuclear weapons.

Iranian President Hassan Rousani called Trump's words "ignorant, absurd and hateful rhetoric - filled with ridiculously baseless allegations".
Asked if Iran would continue to abide by the deal if the U.S. withdrew, Rouhani said his country's commitments "would no longer exist" and it would be free to pursue a new path.
Though Trump has signed temporary waivers on sanctions against Iran, the administration must decide by October 15 whether to recertify Iran as compliant with the nuclear agreement.
"The world will have lost a great opportunity", he declared.
She added that the United States, which has questioned the value of the deal, agreed that Iran was in full compliance of the agreement.
Secretary Tillerson looked surprised when a reporter informed him that the president had already told the press that he had indeed arrived at a final decision, signaling disconnect between the head of government and the top diplomat.
He singled out "the new US administration" in saying it would destroy its own credibility by abrogating global agreements.
In his address to the UN General Assembly, Trump on Tuesday, September 19, called the nuclear deal "an embarrassment" for the United States and Tillerson later confirmed that the agreement must be "revisited". Macron told reporters Tuesday that the 2015 agreement is the best option for now to keep watch on Iran's nuclear program.
