The court found Poland violated its obligations under the European Convention on Human Rights to prevent torture, ensure the right to liberty, and properly investigate allegations a crime had been committed on its territory.

It ordered Poland to pay al-Nashiri 100,000 euros in damages and 130,000 euros to Zubaydah.

"The ruling of the tribunal in Strasbourg on CIA jails is embarrassing for Poland and is a burden both in terms of our country's finances as well as its image," said Joanna Trzaska-Wieczorek, a spokeswoman for the Polish president.

Poland's foreign ministry said a decision had not yet been taken about an appeal. Ministry spokesman Marcin Wojciechowski said the court ruling was premature because Polish prosecutors were investigating the allegations about the CIA jail. That investigation has been running since March 2008.
