TEHRAN, November 29 (IslamOnline.net & News Agencies) - Iran will provide the U.N.'s atomic watchdog with all information required by February, the country's top nuclear official said Saturday, November 29, reiterating a pledge to soon sign an additional protocol to the Non-Proliferation Treaty (NPT).

However, Hassan Rowhani, who handles Iran's nuclear affairs as secretary of the Supreme National Security Council, said the Islamic republic was still refusing to indefinitely suspend its uranium enrichment activities, reported Agence France-Presse (AFP).

"The government must give its authorization to its representative (to the IAEA) to sign (the protocol). It won't be very long," Rowhani told a press conference.

"The director general (of the IAEA, Mohammed el-Baradei) must present his new report in February ... we will put every means at the agency's disposal so it can verify the information which we have provided," asserted the official.

The IAEA resolution was a compromise between the U.S. call to censure Iran and demands from Britain, France and Germany that Iran be rewarded for cooperating since October with the U.N. agency.

It also agreed to make a full declaration of its nuclear activities and suspend uranium enrichment.

But the text of the Wednesday's IAEA resolution also contained harsh words for Iran, in particular a passage warning that any further non-proliferation breaches would be met by stern action.

Tehran insists on the peaceful nature of its nuclear activities and Rowhani refused to rule out future uranium enrichment.

"The suspension of enrichment is provisional and voluntary, to build confidence. There is no question of halting our enrichment activities," he said.

Uranium enrichment is at the center of international concern Iran could be capable of building an atomic bomb. Tehran has said it reserves the right to restart enrichment "at any moment."

"We at least want to be able to supply the fuel for one of our future civil centers," Rowhani said.

"We are going talk with Europeans about modern technology transfer, including nuclear, and about (the delivery to Iran of) fuel," he said.

Despite Tehran's pledges to cooperate fully with the IAEA, the United States is lying in wait for revelations of alleged hidden activities that will clear the way to tougher action, analysts have told AFP.

"American thinking is coalescing around the suspicion that there are more Iranian nuclear sites that haven't yet been made public," Andrew Koch, the Washington correspondent of Jane's Defense Weekly, told AFP.

Following Wednesday's IAEA ruling, diplomats and analysts said the U.S. was clearly calculating that it was only a matter of time before more Iranian violations of nuclear NPT safeguards would be discovered and set off an international uproar that would force the IAEA to take Iran to the U.N.'s highest body in New York.

Koch said U.S. intelligence officials believed there was "still another site somewhere" hidden by Iran, even though Tehran insists it has told all there is nothing more to find in a nuclear program that is strictly for peaceful ends.

Koch said the information could come out in many different ways.

The IAEA has been inspecting Iran's program since February, and its director general has issued three reports, with the latest saying Iran had hidden its production of small amounts of plutonium and enriched uranium.

ElBaradei said the IAEA was now embarked on a "robust" series of inspections to verify that "nuclear activities in Iran are fully declared and are exclusively for peaceful purposes."
