Ukrainian troops rode into the town of Kramatorsk in the eastern Donetsk region on Wednesday in armored personnel carriers flying Russian flags in order to penetrate the town, acting leader of the Batkivshchyna party faction in Ukraine's Verkhovna Rada (parliament) Sergei Sobolev told reporters in Kiev, a Russian Business Channel-Ukraine correspondent reports.
Earlier, Ukraine's acting Defense Minister Mikhail Koval acknowledged the incident.
"Our troops used a guerrilla-style method to penetrate areas controlled by armed units of the Russian Federation and the separatists financed by Russia. I think that this will be reported within three hours or so and you will realize that it was a breakthrough that enabled our units to advance. That's the official information from the defense minister," Sobolev said.
At around 11:30 am on Wednesday, three APCs flying Russian flags reportedly entered Kramatorsk. The Ukrainian Defense Ministry initially denied those reports.
