TOPSHOT-UKRAINE-RUSSIA-CRISIS

TOPSHOT - A technician works to repair a tank at a workshop in the rebel stronghold of Donetsk March 12, 2015. Located in a factory that produces heavy machinery for the mining industry, the workshop has been repairing captured Ukrainian tanks, armoured vehicles and self-propelled guns, as well as Donetsk People's Republic's army hardware for the past 8 months. The ceasefire in eastern Ukraine between Kiev's forces and pro-Russian rebels is largely being observed but is still on "thin ice," an OSCE monitor said Thursday.
