"We also have partners across the ocean - our American colleagues - who, according to a lot of evidence, still favor pushing the Ukrainian leadership towards the path of confrontation," Lavrov told Rossiya 1 channel's news show "Sergey Brilev's News on Saturday".
The minister argues one of the reasons behind the on-going violence in Ukraine is that not all the military forces fighting self-defense squads in the country's south-east are under government control.
"Ukrainian President Petro Poroshenko would like to ease tension and go on with the truce, but there are also other forces among the Ukrainian authorities - there are radicals still controlling or very closely cooperating with armed ultra nationalists, there is the "Right Sector", the battalions of Igor Kolomoysky and other serious groups, who do not obey Ukraine's Central Command and the Commander-in-Chief," Lavrov said.
Poroshenko announced on Friday he was extending the week-long cease-fire for another three days, which was about to come to an end. During the cease-fire sporadic fighting still continued throughout southeastern Ukrainian with both sides of the conflict blaming each other for outbreaks of violence.
Speaking to journalists in Brussels, the Ukrainian president accused Russia of doing nothing to help bring peace back to the country.
Comment: Not Russia's responsibility, Poroshenko! And even then, Russia's done more to stabilize the situation than you and your U.S. masters, who have done nothing but aggravate, provoke, and intensify the crackdown on legitimate dissent in 'your' country.
