Syria's ambassador to the United States said Friday that the CIA fabricated pictures allegedly taken inside a secret Syrian nuclear reactor and predicted that in coming weeks the US story about the site would "implode from within." "The photos presented to me yesterday were ludicrous, laughable," Ambassador Imad Moustapha told reporters at his Washington residence. He refused to say what the building in the remote eastern desert of Syria was used for before Israeli jets bombed it in September 2007. Senior US intelligence officials said Thursday they believe it was a secret nuclear reactor meant to produce plutonium, which can be used to make high-yield nuclear weapons. They alleged that North Korea aided in the design, construction and outfitting of the building. Syria's ambassador to the United Nations, Bashar Ja'afari, pledged on Friday to cooperate with the IAEA and suggested that "the main target of the American CIA allegations against Syria is to justify the Israeli attack against the Syrian side."
