"There were no enemy provocations on the engagement line. No Ukrainian troops were wounded or killed in the clashes," Lysenko told a briefing in Kyiv on Wednesday. He said the Ukrainian military had withdrawn tanks to the agreed distance in the Luhansk region over a short period of time. "Now it's up to the international observers, who have to verify the full absence of Ukrainian tanks in the area near the frontline on a specific site," Lysenko said.
