Abed al-Hajeby, 12, makes his way down a street, on all four limbs, in Sanaa November 13, 2012. Abed and his brothers Nayef, 13, and Hassan, 25, suffer from a congenital genetic disability that has disfigured their legs and spines. As a result of this, they are unable to walk upright and have only ever moved around on all four limbs. The youths spend their time begging on the streets of Sanaa.
