Passengers look out of the windows of a train as it moves past local residents, and an armed man (front L) wearing a black and orange ribbon of St. George - a symbol widely associated with pro-Russian protests in Ukraine, and Ukrainian servicemen on an armoured personnel carrier in Kramatorsk, April 16, 2014. Separatists flew the Russian flag on armoured vehicles taken from the Ukrainian army on Wednesday, humiliating a Kiev government operation to recapture eastern towns controlled by pro-Moscow partisans.
