UKRAINE-RUSSIA-CRISIS-POLITICS

A pro-Russian activist, holding a wooden club and a shield, guards a barricade outside a regional police building seized by the armed separatists to prevent storming by the Ukrainian police special team in the eastern city of Slavyansk on April 13, 2014. Ukraine today launched an "anti-terrorist operation" in Slavyansk, where pro-Russian gunmen have seized police and security services buildings, Interior Minister Arsen Avakov said. "Units from all of the country's force structures are participating. May God be with us," the minister wrote on his Facebook page.
