Ukraine forces pull back from air terminal

(ANSA) - Rome, January 22 - Ukraine troops on Thursday have withdrawn from Donetsk airport's main terminal, scene of bitter fighting in recent weeks, as pro-Russian rebels and the government trade blame for a bus attack that killed 13.
    The government said the military still retained control of parts of the airport, but six soldiers had died and 16 had been wounded.
    In the centre of the rebel-held city, shelling hit a bus, killing 13 people.
    Rebels paraded captured Ukrainian soldiers at the scene, as onlookers shouted abuse and beat or pelted them with debris from the blast site.
    The attack came nine days after a shell also killed 13 people on a bus in the village of Buhas outside Volnovakha, 35km (22 miles) south-west of Donetsk.
