2014年CRI 乌克兰出兵东部 普京谴责称是犯罪（在线收听）

Russia is slamming Ukraine for its military crackdown in the eastern city of Slavyansk, saying it is going to wipe out all hope for the viability of the Geneva agreements.

Russian President Vladimir Putin is characterizing the operation as possibly "criminal."

He suggests the operation has "crossed out" the agreements reached in Geneva on April 17th.

Moscow also says it is "extremely concerned" for the safety of Russia's presidential special envoy Vladimir Lukin, who is in the conflict zone.

This comes as Ukrainian forces sweep into Slavyansk to try to clear the city of pro-Russian forces.

The fighting has already resulted in two Ukranian helicopters being shot down, with both pilots killed.

Several others have reportedly been wounded in the offensive, which began at dawn on Friday.
