TEHRAN - Iran's state IRIB TV announced Tuesday that the next round of nuclear talks between the Islamic republic and the International Atomic Energy Agency (IAEA) was rescheduled for Feb 13.

Gill Tudor, the IAEA spokesperson, told IRIB in Vienna on Monday that the next round of Iran-IAEA talks would be held on February 13 in Tehran.

After the two-day talks ended here last Thursday, both Iran and the IAEA announced that a new round of talks would be held on February 13 in Tehran.

Iran and the IAEA failed to reach an agreement on the investigation of the disputed nuclear program, but Iran said the negotiations were a step forward.
