KIEV - Fighting raged on Saturday at the main airport of Ukraine's city of Donetsk as separatists resumed attempts to break the tenuous grip of government forces on the complex and Kiev's military said three more Ukrainian soldiers had been killed.
With attempts to restart peace talks stalled, pro-Russian rebels have stepped up shelling attacks to break the resistance of government troops dug in at the airport, itself a wrecked hulk battered by months of war.
Though its runways are cratered and it has long ceased to function, the airport has symbolic value for both sides and has become the main flashpoint in the fighting as prospects for fresh peace talks have dimmed.
A planned meeting of representatives from Ukraine, Russia and the Organization for Security and Cooperation in Europe and separatist leaders on the Ukraine crisis failed to materialize in the Belarussian capital Minsk on Friday.
A meeting of the so-called 'contact group' is seen as vital for getting the warring parties to observe a real ceasefire.
"In the past 24 hours three Ukrainian service personnel have been killed and 18 wounded. Yesterday evening we succeeded in evacuating the wounded from the airport," military spokesman Andriy Lysenko said.
Separatists were concentrating their fire on Saturday on the airport's new terminal and its weather station.
