A European investigator said today he has proof Poland and Romania hosted secret CIA prisons under a post-9/11 pact to hunt down "high value" terrorist suspects wanted by the United States.
Swiss senator Dick Marty said Poland housed some of the CIA's most sensitive prisoners, including Khalid Sheikh Mohammed, who says he masterminded the September 11th 2001, attacks on the United States that killed almost 3,000 people.
"There is now enough evidence to state that secret detention facilities run by the CIA did exist in Europe from 2003-2005, in particular in Poland and Romania," Mr Marty said in a report for the Council of Europe human rights watchdog.
He said US intelligence and other sources told him the two European Union members hosted the secret jails under a special CIA programme, created by President George W. Bush's administration after 9/11 "to 'kill, capture and detain' terrorist suspects deemed of 'high value'".
Mr Marty said the former president of Poland and the current and former presidents of Romania knew and approved of their countries' roles in a "global spider's web" of secret CIA detentions and transfers, known as extraordinary renditions.
He said the proof of his charges was confirmed in interviews with over 30 serving, retired or contract workers for US or European intelligence services, but he had not seen the text of any US agreement with Poland or Romania on secret prisons.
Germany and Italy had used "state secrecy" to obstruct investigations, said Mr Marty. His report, after a 19-month probe, could embarrass European governments, which have criticised the detention without trial of suspects at Guantanamo Bay.
Mr Marty's report was issued as 26 Americans, mostly suspected CIA agents, went on trial in absentia in Italy for kidnapping a Muslim there in 2003 and flying him to Egypt as part of Washington's rendition policy.
The Council of Europe's evidence could be valid in some courts if rules allowed judges to accept it while guaranteeing the confidentiality of the source.
The report found Poland's then-president Aleksander Kwasniewski and three other named officials were aware of and could be held accountable for the CIA secret prisons in Poland.
Suspects were flown from Kabul and elsewhere to Szymany airport in northern Poland, with dummy flight logs submitted to disguise the destination, Marty said. They were met at the runway by teams of Americans in vans and driven through a pine forest to the alleged detention centre at nearby Stare Kiejkuty.
Mr Marty said CIA sources confirmed to him that Khalid Sheikh Mohammed and another top al Qaeda captive, Abu Zubaydah, were held in Poland and subjected to "enhanced interrogation techniques", which he called a euphemism for torture.
The Polish Foreign Ministry said there were no such secret centres and former Defence Minister Jerzy Szmajdzinski, one of those named, told Reuters: "Marty's work is pure political fiction...It is a waste of time and a waste of money."
Romanian President Traian Basescu, former president Ion Iliescu and former defence minister Ioan Mircea Pascu were among those who "knew about, authorised and stand accountable" for Romania's role in the CIA programme, Marty said.
The Romanian Foreign Ministry said the report contained "no evidence to confirm these allegations, except for unnamed sources, whose credibility cannot be estimated".
The European Commission said it was "very concerned indeed" and urged Romania and Poland to hold independent investigations.
