Since the unrest in eastern Ukraine surged anew in early January, the separatists have made notable strides in clawing territory away from the government in Kiev. Their main offensive is now directed at Debaltseve — a government-held railway junction once populated by 25,000 people that lies between the rebel-held cities of Luhansk and Donetsk. Almost 2,000 residents have fled in the last few days alone. (AP Photo/Vadim Braydov) (The Associated Press)
