Tehran - Tehran on Wednesday categorically denied a meeting between officials of Iran and the United States occurred at a UN conference in the Netherlands, the Mehr news agency reported.

US Secretary of State Hillary Rodham Clinton had said the US special envoy to Afghanistan and Pakistan, Richard Holbrooke, met briefly Tuesday with Iranian Deputy Foreign Minister Mehdi Akhunzadeh at the conference on Afghanistan in The Hague.

"There has been neither an official nor an unofficial meeting at the Afghanistan conference, and we deny all reports in this regard," Foreign Ministry spokesman Hassan Ghashghavi told the news agency.

The spokesman also denied that Holbrooke gave Akhundzadeh a letter demanding the safe return of Robert Levinson, a former agent with the US Federal Bureau of Investigation allegedly held in Iran, and the release of Iranian-American journalist Roxana Saberi from the Evin prison in Tehran. (dpa)
