Turkish intelligence chief Ibrahim Kalin says Qatar is scheduled to host a meeting next week between US Vice President JD Vance and Iran's Supreme National Security Council Secretary Mohsen Razai.
According to the Doha News newspaper and the Masri Al-Ahram newspaper, he said at a meeting in Ankara on Monday that this meeting could be an important opportunity for progress in negotiations between Tehran and Washington.
Mr Kalin said Turkey and other mediators were working on a seven-point plan to reach an agreement between the US and Iran.
However, an Iranian official denied the possibility of a meeting between Vance and Razai.
