Tehran  - A delegation from the United Nations nuclear watchdog is to revisit Iran next week, ISNA news agency reported Friday.

The International Atomic Energy Agency (IAEA) delegation, headed by IAEA deputy Olli Heinonen, is scheduled to visit Tehran on Monday to continue talks held earlier this week, an unnamed source told ISNA without giving further details.

The two sides held earlier this week intensive two-day talks, reportedly over allegations that Iran was pursuing secret nuclear weapons studies.

Iranian Foreign Minister Manouchehr Mottaki, however, termed the visit by Heinonen to Tehran just a routine act and rejected Western press reports that the talks were solely focused on the new allegations.

Mottaki also played down last Wednesday's remarks by IAEA head Mohamed ElBaradei, who had termed Iran's agreement to clarify alleged nuclear weapons studies by May as a "milestone" in solving questions about the country's nuclear programme.

The foreign minister said that Iran had already replied to all IAEA questions during the previous year and also taken a quite clear stance towards all "baseless allegations."

However, he did not clarify whether Iran would eventually reply to the allegations by May or not but just said that Tehran would continue cooperation with the IAEA "as a normal member" and within the framework of the Nuclear Non-Proliferation Treaty. (dpa)
