"The Russian president remarked that the sharp escalation of the conflict has placed the country, in effect, on the verge of civil war," the Kremlin said in a statement on telephone talks between the two leaders.
But the leaders both "emphasised the importance" of the planned four-way talks on Ukraine on Thursday between top diplomats of Russia, the European Union, the United States and Ukraine.
"The hope was expressed that the meeting in Geneva can give a clear signal to return the situation to a peaceful framework," the statement said.
The Kremlin statememt described the actions of the Ukrainian army in eastern Ukraine as an "anti-constitutional course to use force against peaceful protest actions."
