Russian President Vladimir Putin and Ukrainian President-elect Petro Poroshenko have called for a quick end to the bloodshed in eastern Ukraine, Russian officials have said.
The two leaders were meeting for the first time since Mr Poroshenko’s election, at a D-Day event in France.
Mr Putin also spoke briefly to the US president, the White House said.
Fighting continues, with government forces reportedly launching a tank attack near rebel-held Sloviansk.
The Ukrainian authorities have announced an “active phase” of what they call an anti-terrorist operation in and around Sloviansk, which was seized by pro-Russian militants several weeks ago.
Separately, Ukrainian media reported that one member of the security forces had been killed and several wounded in a mortar attack outside the city.
