Talks between the United Nations' nuclear watchdog and Iran aimed at resolving concerns about Iran's atomic program have broken up without an agreement.
The International Atomic Energy Agency's (IAEA) chief inspector, Herman Nackaerts, told journalists after the meeting in Vienna on August 24 that "important differences remain" that prevented agreement.
Nackaerts added that "at the moment" no further talks have been scheduled.
The IAEA is probing suspicions that Iran has carried out covert nuclear weapons research work -- allegations that are denied by the Islamic republic.
Western diplomats say Iran has installed many more uranium enrichment machines at its Fordow facility, despite UN sanctions aimed at curbing Tehran's enrichment activities.
Western diplomats also claim Iran is cleaning up facilities at its Parchin site to remove evidence of illicit activity.
Talks between Iran and six world powers ended in failure in June.
