Europe's human rights court has heard cases concerning the rendition of two men suspected of terrorist acts to secret CIA detention sites.
The hearings marked the first time Europe's role in the U.S. agency's "extraordinary rendition" of terror suspects had reached the European Court of Human Rights in Strasbourg.
Lawyers for the two suspects accuse Poland of human rights abuses in connection with its role in what they say was their torture in a remote Polish prison.
One case concerns Saudi national Abd al-Rahim al-Nashiri, who faces terror charges for allegedly orchestrating the Al-Qaeda attack on the "USS Cole" in 2000 that killed 17 sailors.
The second case involves Palestinian terror suspect Abu Zubaydah.
Both are imprisoned at the U.S. military detention camp at Guantanamo Bay in Cuba.
The court's ruling is expected at a later date.
