Supporters of Yemen's President Ali Abduallah Saleh stand on flag poles celebrating his return to Sanaa, Yemen, Friday, Sept. 23, 2011. Saleh made a surprise return to Yemen on Friday after more than three months of medical treatment in Saudi Arabia in a move certain to further inflame battles between forces loyal to him and his opponents that have turned the capital into a war zone.
