Palestinian maths teacher Ali Wahdan moves his motorised wheelchair to enter his makeshift shelter, in Beit Hanoun town, in the northern Gaza Strip July 6, 2015. Wahdan, a maths teacher from Gaza, lost his wife, 11 members of his family and a leg to Israeli bombardment of the town of Beit Hanoun, in the north of the Gaza Strip, during last year's war between Israel and Hamas. Nearly 12 months on, doctors have decided to amputate his other leg. It is a cruel reminder of how little progress he has made since the 50-day war. In almost all respects, his life and prospects have crumbled. Picture taken July 6, 2015. REUTERS/Suhaib Salem
