Ukraine crisis: More buildings seized in east

Armed men have seized a police station and a security services building in eastern Ukraine, according to officials.

Police said the men fired shots and used stun grenades to seize the offices in Sloviansk, near the Russian border.

Meanwhile, a gun battle has erupted in the eastern Ukrainian town of Kramatorsk, according to the Ukrainian acting interior minister.

Pro-Russian activists have seized government buildings elsewhere in east Ukraine in recent days and Kiev has accused Moscow of orchestrating the unrest.
