The six negotiators on the Iranian nuclear issue will meet in the coming days at the level of foreign ministries'' political directors due to the postponement of ministerial talks, France''s Foreign Ministry said.

Russian Foreign Minister Sergei Lavrov earlier said a meeting on Iran involving the foreign ministers of Russia, China, the United States, France, Britain and Germany was canceled as the parties had failed to fix a date due to their busy schedule at the current UN General Assembly session.

"We would like this meeting to take place in New York at the level of political directors," a French Foreign Ministry spokesman quoted minister Bernard Kouchner as saying.

The International Atomic Energy Agency, the UN nuclear watchdog, said on Monday it had not been able to make much progress on the issue of a possible military aspect to Iran''s nuclear program.

At a meeting with UN Secretary General Ban Ki-moon in New York on Tuesday, Iranian President Mahmoud Ahmadinejad reiterated that the Islamic Republic''s nuclear program was entirely peaceful and dismissed U.S. accusations that Tehran was striving to develop nuclear weapons.
