In this Thursday, March 27, 2014 photo, Ziad Zehori, 24, left, who lost his leg in a Syrian government airstrike on Sept. 25, 2013, sits as Mohammed Kurdi, right, a physiotherapist for Handicap International, checks his thigh, at the Syrian refugee camp in Zahleh, in the Bekaa valley, Lebanon. Syria’s civil war, which entered its fourth year last month, has killed more than 140,000 people. An often overlooked figure is the number of wounded more than 500,000, according to the International Committee of the Red Cross. An untold number of those, there’s no reliable estimate even, have suffered traumatic injuries that have left them physically handicapped. (AP Photo/Bilal Hussein)
