Ukraine has denied reports there are secret prisons run by the U.S. Central Intelligence Agency on Ukrainian territory.

Foreign Ministry spokesman, Vasilily Filipchuk Tuesday called a Swiss media report saying Ukraine allowed the covert U.S. interrogation centers on its soil "absurd."

Russia's Novosti news agency says Ukraine's penitentiary and security service officials also dismissed the Swiss report.

The Swiss newspaper Sonntags-Blick says Swiss security officials intercepted an Egyptian government document mentioning secret CIA prisons in several eastern European nations, including Ukraine, Romania, Macedonia, Bulgaria as well as in Serbia's province of Kosovo.
