In June 2008, a "New York Times" article claimed, citing unnamed CIA officers, that Khalid Sheikh Mohammed was held in a secret facility in Poland near Szymany Airport, about north of Warsaw and it was there where he was interrogated and the waterboarding was applied. It is claimed that waterboarding was used about 100 times over a period of two weeks before Khalid Sheikh Mohammed began to cooperate. In September 2008, two anonymous Polish intelligence officers made the claims about facilities being located in Poland in the Polish daily newspaper "Dziennik". One of them stated that between 2002 and 2005 the CIA held terror suspects inside a military intelligence training base in Stare Kiejkuty in north-eastern Poland. The officer said only the CIA had access to the isolated zone, which was used because it was a secure site far from major towns and was close to a former military airport. Both Prime Minister Leszek Miller and President Aleksander Kwasniewski knew about the base, the newspaper reported. However, the officer said it was unlikely either man knew if the prisoners were being tortured because the Poles had no control over the Americans' activities. On January 23, 2009, "The Guardian" reported that the CIA had run black sites at Szymany Airport in Poland, Camp Eagle in Bosnia and Camp Bondsteel in Kosovo. The United States has refused to cooperate with a Polish investigation into the matter, according to the Helsinki Foundation for Human Rights.
