Battle Zones: Ukraine & Syria

From PBS and Frontline: FRONTLINE goes inside the raging battle zones of Ukraine and Syria. In Ukraine, with personal and dramatic footage, FRONTLINE reveals the deep-seeded hatreds between right-wing Ukrainian nationalists with historic ties to the Nazis, and violent pro-Russian separatists vying for control of the country. And in Syria, FRONTLINE finds rebel fighters who say they're being secretly armed and trained by the United States.
