An official source close to the Iranian negotiating team told Press TV on Friday that no agreement had been reached between Iran and the UN nuclear agency over the date of a new round of talks.
The official further pointed out that the issue had been discussed in a meeting but no deal was reached.
On Thursday, the Associated Press quoted two anonymous diplomats as saying that Iran and the IAEA had agreed to hold new talks in mid-May.
Iran and the IAEA last met in Tehran in mid-February and mid-January.
The United States, Israel, and some of their allies have repeatedly accused Iran of pursuing non-civilian objectives in its nuclear energy program, an allegation Iran strongly rejects.
Tehran maintains that as a committed signatory to the Non-Proliferation Treaty (NPT) and a member of the IAEA, it is entitled to develop nuclear technology for peaceful purposes.
The IAEA inspectors have conducted numerous inspections of Iran’s nuclear facilities but have never found any evidence showing diversion from peaceful purposes in the Iranian nuclear energy program.
