15 Ukrainian troops killed escaping rebel blockadeFriday 08 August 2014 15.59
Ukrainian army units that had been trapped by separatists on the border with Russia have broken out of the blockade and rejoined government forces.
However, 15 soldiers and border guards were killed in the operation, the Ukrainian military said.
Military sources quoted by Ukrainian media said Ukrainian units had been effectively encircled by the rebels on a section of the border with Russia south of the town of Luhansk and east of the main regional city of Donetsk.
After government forces opened up an escape corridor, the trapped units were able to force their way out, military sources quoted by the media said.
"Seven service staff and eight border guards were killed and 79 injured," military spokesman Andriy Lysenko told journalists.
Government forces say they are gradually tightening the noose around the heavily armed pro-Russian separatists whom they have been battling since mid-April.
The United Nations High Commissioner for Human Rights said the conflict has cost the lives of more than 1,100 people in all, including government forces, rebels and civilians.
The latest military deaths from the fighting in the Russian-speaking east of Ukraine push the death toll among government forces alone to more than 400.
