Washington: The fourth round of nuclear talks between the US and Iran is scheduled to take place on May 3 in Europe. This development comes after a report from Axios, which cited a US official on Saturday.

According to Anadolu Agency, an American official described the third round of discussions held in Oman as lasting over four hours, with both direct and indirect engagement. The official characterized these discussions as "positive and productive," but acknowledged that there is still significant work ahead to reach a deal.

Omani Foreign Minister Badr Albusaidi had previously announced that Washington and Tehran would reconvene on May 3. The US official who spoke to Axios confirmed that the upcoming talks would occur in Europe, though the specific country has not been disclosed. The second round of talks was previously held in Rome, Italy, on April 19.

Iran's Foreign Minister Abbas Araghchi noted that the latest round of discussions was "more serious than before," with both parties gradually delving into more technical details related to nuclear issues. Araghchi expressed hope while maintaining caution, stating that the ongoing negotiations with Washington have provided optimism for potential progress.

US President Donald Trump has warned of possible military action against Iran if a new agreement is not reached to replace the 2015 nuclear deal established during the Barack Obama administration. Trump has reiterated his stance that Iran "cannot have a nuclear weapon."
