Ukraine and Russia traded blame Sunday for a shootout at a checkpoint manned by pro-Russia insurgents in eastern Ukraine that left at least three people dead and others with gunshot wounds.
The identity of the attackers remained unclear. Russia blamed militant Ukrainian nationalists and the Ukrainian government said the attack near the city of Slovyansk was staged by provocateurs from outside the country.
The armed clash appeared to be the first since an international agreement was reached last week in Geneva to ease tensions in eastern Ukraine, where armed pro-Russia activists have seized government buildings in at least 10 cities.
Ukraine and many in the West fear that such clashes could provide a pretext for Russia to seize more Ukrainian territory.
