According to an article in the
Washington Post more recently, the Czechs backed away from the claim: "After months of further investigation, Czech officials determined last year that they could no longer confirm that a meeting took place, telling the Bush administration that al-Ani might have met with someone other than Atta." This perception seems confirmed by an associate of al-Ani's who suggested to a reporter that the Czech informant had mistaken another man for Atta. The associate said "I have sat with the two of them at least twice. The double is an Iraqi who has met with the consul. If someone saw a photo of Atta he might easily mistake the two."
In 2014 Jiří Růžek, the former head of Czech intelligence agency
BIS, published his memoirs. Here he claims that the USA tried to push Czech prime minister
Miloš Zeman to announce that 9/11 attack was planned with the help of Iraq in Prague. All blame for the false cause of conflict would then fall on Czech authorities
