The European Court of Human Rights has found that Poland violated the EU Convention on Human Rights by allowing the CIA to detain two al-Qaeda suspects on Polish territory.
The case was brought by two Saudi-born men who said they were flown in secret to a CIA-run jail in a Polish forest and subjected to treatment that amounted to torture.
Polish officials have denied the existence of the CIA jail. The US has acknowledged that it kept al-Qaeda suspects in facilities outside the US, but has not said where.
The EU court ruled that Poland violated articles around the prohibition of torture, the right to liberty and the right to an effective investigation of their allegations.
Poland has been ordered to pay the men 230,000 euros.
