Emmanuel Karenzi Karake is accused by Spain of war crimes. He was arrested at Heathrow Airport on Saturday by British police acting on a European warrant.

Judge Quentin Purdy said a full extradition hearing would be held starting on Oct. 29. The judge granted Karake conditional bail and said he would be released from police custody after meeting several court-ordered conditions, including posting bail of 1 million pounds ($1.57 million).
