Anwar Tarawneh (C), the wife of Jordanian pilot Maaz al-Kassasbeh, who was captured by Islamic State (IS) group militants on December 24 after his F-16 jet crashed while on a mission against the jihadists over northern Syria, takes part in a rally calling for the release of her captive husband in the Jordanian capital Amman on February 3, 2015. Jordan vowed to do all it could to save the pilot held by IS after the jihadists killed a Japanese journalist they had been holding. IS has been demanding the release of an Iraqi jihadist on death row in Jordan in exchange for Kassasbeh's life, and Amman said it would hand her over if given proof that he is still alive.
