[Iranian Source: U.S. Leak of Cancelled Talks Shows Lack of Sincerity] Odaily Planet Daily reports that a senior Iranian source stated, 'The U.S. leaking the news of cancelled talks demonstrates its lack of sincerity.' The source emphasized that Iran will not accept negotiations on any topics outside of the nuclear issue. Earlier, two U.S. officials revealed that the U.S. government had formally informed Iran on the 4th that it rejected Iran's request to change the originally scheduled meeting location and format on the 6th. The two sides had previously agreed to hold talks in Istanbul with the participation of multiple international observers, but on the 3rd, Iran requested to move the negotiations to Oman and conduct them in a bilateral format. After evaluation, the U.S. determined that this move could weaken the effectiveness of multilateral coordination and thus insisted on the original arrangement.
