The UN nuclear watchdog IAEA will publish its latest report on Iran''s nuclear programme as early as Monday afternoon, sources close to the agency said Sunday.

According to those sources, it was "possible but not certain" that the International Atomic Energy Agency would publish the document on Monday.

The latest report comes after repeated talks between IAEA deputy chief Olli Heinonen and Iranian officials in Tehran in August.

The IAEA has been investigating Iran''s nuclear activities for four years, but has so far been unable to say once and for all whether the activities are entirely peaceful.

The United States and other western nations fear Iran is trying to build a nuclear bomb.

Tehran, on the other hand, insists its nuclear programme is aimed solely at generating energy for its growing population.

In its latest Iran report published in May, the IAEA accused Tehran of withholding key information on alleged attempts to make nuclear arms.
