ABC News first reported that Lithuania was one of three eastern European countries, along with Poland and Romania, where the CIA secretly interrogated suspected high-value al-Qaeda terrorists, but until now the precise site had not been confirmed. Read that report here.
The CIA purchased the property in March 2004, the same month Lithuania marked its formal admission to NATO. Poland joined NATO in 1999, and Romania joined in 2004.
"The older members, the original 15 members of NATO, would never have said yes to something like this," said former White House counterterrorism czar Richard Clarke, now an ABC News consultant. "But the new members were easy to please."
The CIA opened the prison in September 2004, and closed it in November 2005, former CIA officials told CIA News.
The CIA declined to talk about the prison. "The CIA's terrorist interrogation program is over," said CIA spokesman Paul Gimigliano. "This agency does not discuss publicly where detention facilities may or may not have been."
The building is now owned by Lithuanian intelligence, which refused to let ABC News past its gates.
