By Gram Slattery and Humeyra Pamuk UNITED NATIONS, Sept 22 (Reuters) - US President Donald Trump used his UN General Assembly speech on Tuesday to make the case for his war on Iran, arguing he has prevented Tehran from obtaining a nuclear weapon and warning that he could "annihilate the Islamic Republic" if no deal is reached to end the conflict.

U.S. officials met with Iranian leaders on Tuesday on the sidelines of the United Nations General Assembly meeting, President Donald Trump said.

Members of the Cuban and Iranian delegations walked out at points during Trump’s speech.
