Ukraine troops retake airport

The offensive brought fighting close to the industrial city of Donetsk itself, centre of a pro-Russian rebellion, while shelling intensified in other parts of the region, known as the “Donbass”.
With attempts to restart peace talks stalled, pro-Russian rebels have stepped up attacks in the past week and casualties have mounted, including 13 civilians killed in an attack on a passenger bus, which Kiev blamed on the separatists.
