Rebel attack leaves dead and wounded among Ukraine forces: National Guard

KIEV (Reuters) - Pro-Russian separatists attacked Ukrainian government forces with mortar fire on Friday in a city in the rebellious east of the country, killing and wounding a number of them, the National Guard said. It said the rebels, operating from the precincts of a nearby church, fired on a government forces checkpoint in Slaviansk, which has been controlled by separatists since early April. "As a result of the mortar fire there are dead and wounded among law enforcement servicemen," the national guard said in a statement on its website, without disclosing a precise casualty figure.
