Lawmakers at the European Parliament on Thursday demanded the United States name the locations of secret CIA prisons, after US President George W. Bush disclosed that terror suspects have been held at overseas facilities. "The location of these prison camps must be made public," said German Socialist Wolfgang Kreissl-Doerfler, who sits on a special EU assembly committee investigating the CIA's alleged operation of secret prisons in Europe. "We need to know if there has been any complicity in illegal acts by governments of EU countries or states seeking EU membership." Bush did not say where the facilities were located, but the European Parliament's investigation has focused on allegations that several secret prisons were run in Eastern Europe. The EU parliament's investigation's deputy leader, British Liberal Democrat Sarah Ludford, said Bush's admission "exposes not only his own previous lies. He also exposes to ridicule those arrogant government leaders in Europe who dismissed as unfounded our fears about extraordinary rendition."
