Small groups of Ukrainian troops from Debaltseve head north

ARTEMIVSK, Ukraine (Reuters) - Weary Ukrainian troops, some in columns, some in cars, began arriving on Wednesday from the besieged town of Debaltseve in Artemivsk, about 30 km (18 miles) to the north, a Reuters witness said.

Reuters photographer Gleb Garanich said: "Some were by themselves. Some were in columns and others were in cars. They looked very tired and their faces were dirty from battle."
