Ukraine re-takes key cities from pro-Russian rebels

Separatist rebels in Ukraine have withdrawn from several strongholds in the Donetsk region following an offensive by government forces.

Pro-Russian gunmen abandoned the cities of Sloviansk and Kramatorsk, as well as some smaller towns, in the north of Donetsk region.

But they vowed to continue their fight from the city of Donetsk, describing the withdrawal as a tactical retreat.
