Ukrainian government troops have taken control of an airfield blockaded by pro-Russia armed groups in the eastern city of Kramatorsk, as part of what Kiev is calling an 'anti-terrorist operation'. The operation there is part of a wider offensive on gunmen who are occupying government buildings across the region. Casualties have been reported on both sides, but the Ukrainian defence ministry denies that any of its troops have been injured. Al Jazeera's Kim Vinnell reports from Kramatorsk.
