Ukraine crisis: Russia calls for immediate ceasefire

Ukrainian forces have withdrawn from the airport of the eastern city of Luhansk following clashes with pro-Russian rebels, military officials say.

The announcement came after the two sides were engaged in all-night fighting.

Russian Foreign Minister Sergei Lavrov has urged negotiators meeting in the Belarus capital, Minsk, to make an "immediate ceasefire" their priority.
