In this citizen journalism image provided by the Local Coordination Committees in Syria, anti-Syrian regime protesters, burn tires and wave Syrian revolution flag during a demonstration in the suburb of Daraya, Damascus, Syria, on Saturday Feb. 4, 2012. Russia and China vetoed a U.N. Security Council resolution backing calls for Syrian President Bashar Assad to step down, despite international outrage Saturday over a devastating bombardment of the city of Homs by his regime's forces. Activists said more than 200 were killed in the bloodiest episode of the nearly 11-month uprising.
