Following reports on "black site" prisons in Poland, ABC News is now reporting that a third jail existed in the Lithuanian capital Vilnius. According to the report, as many as eight prisoners were held there for at least one year.

The United States is believed to have used the third black site prison in Europe to hold high-value al-Qaida suspects after the Sept. 11 terrorist attacks and to question them using "special interrogation techniques." These included the simulated drowning of prisoners through the practice known as waterboarding. With the development, the debate in America over government interrogation techniques and torture appears to be taking on a greater European dimension.

ABC News reports that the site wasn't closed until late 2005, after newspapers and TV stations first reported on secret prisons in Europe used by the US after the 9/11 attacks. The broadcaster cited former CIA sources either directly involved or briefed on the secret program to detain the suspected al-Qaida terrorists in Europe.
