Riot policemen stand guard as they are hit by fire caused by molotov cocktails hurled by anti-government protesters during clashes in Kiev Feb 18, 2014. Ukrainian riot police charged protesters occupying a central Kiev square early on Wednesday after the bloodiest day since the former Soviet republic, caught in a geopolitical struggle between Russia and the West, won its independence more than 22 years ago. At least 18 people, including seven policemen, died on Tuesday during hours of violence between security forces and civilians who have staged protests against President Viktor Yanukovich since last November.
