Egyptian police who were seized in Sinai by kidnappers are seen upon their arrival at Almaza military Airbase in Cairo on May 22, 2013 following their release, as President Mohammed Morsi vowed to bring the perpetrators to justice and appealed to residents of the lawless peninsula to disarm. The conscripts, seized at gunpoint last week as they were returning from a leave of absence, arrived in Cairo following a joint army and police sweep of Sinai that led to their release, the army said.
