The Spanish judge's investigation concerns 10 CIA-chartered flights through the Balearic islands between January 2004 and January 2005.


According to the text seen by AFP, he is seeking information concerning the suspected transport of Khaled el-Masri, Ahmed Agiza, Mohammed  al-Zary, Hassam Oussama Mustafa Nasr, Bisher al-Rawi, Yamil el-Banna, Maher Arar, Muhammad Bashmila, Salah Ali Qaru, Mohammed Zammar et Binyam Mohamed al-Habashi.


European Union parliamentary inquiries into CIA flights through Spain have embarrassed the Socialist government, which denies that Spanish territory has been used for the illegal transfer of suspected terrorists.


The EU investigations called the Spanish Balearic archipelago an  "important transit base" for the US intelligence agency.
