Germany has issued arrest warrants for 13 suspected CIA agents for their roles in the “extraordinary rendition” of Khaled al-Masri. Meanwhile, as public outrage in Europe over the abduction and torture of terror suspects grows more intense, court proceedings in Italy could lead to the indictment of 25 alleged CIA agents.
German arrest warrants are not valid in the US but if the suspects were to travel to the European Union they could be arrested.
Mr Masri says he was abducted by US agents in the Macedonian capital, Skopje, on 31 December 2003.
He is seeking to sue the US government over his detention, but in May a judge dismissed a lawsuit he filed against the CIA, citing national security considerations.
The US government is not assisting the German authorities with the case.
Meanwhile in the Italian city of Milan, court hearings to decide whether to indict 25 alleged CIA agents and several Italians accused of kidnapping a Muslim cleric in 2003 are under way.
