VIENNA (AFP) - The UN's International Atomic Energy Agency (IAEA) said Saturday a team of its inspectors arrived in Iran to verify information Tehran has revealed about its nuclear program this week. "They arrived in the middle of the night," IAEA spokeswoman Melissa Fleming told AFP from the UN watchdog's headquarters in Vienna, adding that the inspectors would remain in Iran for "several days."

The visit comes after Tehran on Thursday handed the IAEA a report with information about its nuclear program.

It did so to allay international concerns over its nuclear program.

According to IAEA spokesman Mark Gwozdecky the inspection team comprises "half a dozen inspectors" and is led by IAEA chief inspector for Iran Ollie Heinonen.

"We are in a new phase and our first priority is to analyze the declaration (by Tehran) to satisfy ourselves that Iran has come clean," Gwozdecky said.

Iran's ambassador to the IAEA, Ali Akbar Salehi, said Friday that Iran in its report to the watchdog admits that it had failed to meet international nuclear safeguards commitments but he again denied that Iran was seeking nuclear weapons.
