Brothers Hassan al-Hajeby, 25, Nayef al-Hajeby, 13, and Abed al-Hajeby, 12, (L-R) watch a youth cycling by as they beg on a street in Sanaa November 13, 2012. The Al-Hajeby brothers 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. REUTERS/Mohamed al-Sayaghi (YEMEN - Tags: SOCIETY POVERTY HEALTH)
