MOSCOW (Reuters) - When Islamic State fighter Marat Nurmagomedov escaped from Syria to Turkey after becoming disillusioned with the militant group, he was unable to return home to Russia for fear of arrest.

Instead, he managed to obtain a passport under another name and flew from Istanbul to Ukraine, whose ability to identify him as a terrorism suspect was hindered by a lack of intelligence sharing between Moscow and Kiev.
