US President Donald Trump said on Tuesday that Iran has become more aggressive in the nuclear talks.
Trump added in his remarks today that "it's surprising and disappointing to me. But we'll meet again, and we'll see what happens."
He noted that the two sides remain at odds over whether the country will be allowed to continue enriching uranium on Iranian soil.
Trump said the next round of talks between the United States and Iran will take place next Thursday, while a senior Iranian official and a US official said it is unlikely to take place that day.
