By Parisa Hafezi, John Irish DUBAI (Reuters) -Iranian and U.S. negotiators resumed talks on Friday in Rome to resolve a decades-long dispute over Iran's nuclear ambitions, Iranian media reported, despite Tehran warning that a new deal might not be possible amid mutually exclusive demands.

Iran’s Foreign Minister Abbas Araghchi says talks were ‘one of the most professional rounds of negotiations’ yet.

Trump in his first term in 2018 ditched a 2015 nuclear pact between major powers and Iran. Since returning to office this year, he has restored a "maximum pressure" campaign on Tehran and reimposed sweeping US sanctions that continue to hobble the Iranian economy.
