Russian news agencies quoted Foreign Minister Sergei Lavrov as making the comments to reporters on June 12.
Lavrov called for an immediate investigation into the alleged use of "indiscriminatory weapons," such as incendiary bombs, by Ukrainian military forces.
The minister also said Moscow is not bringing up the issue of sending peacekeeping forces to Ukraine for the time being, saying the situation has not gone "that far."
Lavrov added that Russia is presenting a draft resolution to the United Nations Security Council on the situation in Ukraine that calls on the Ukrainian government to start implementing the OSCE road map for resolving the crisis.
Lavrov says fighters in E. Ukraine are ready for ceasefire, but Kiev must stop first.

Lamberto Zannier met with the refugees at a camp in Dmitriadovka, some 40 kilometers from the Ukrainian border, on June 12.
The Interfax news agency quoted him as saying the conflict in the east "is craziness which must be stopped."
He proposed that a roundtable conference be held between former Ukrainian Presidents Leonid Kravchuk and Leonid Kuchma, the current Ukrainian authorities, and representatives of the pro-Russian separatists.
On June 10, Ukrainian President Petro Poroshenko ordered the creation of humanitarian corridors to allow civilians to escape the eastern regions where government forces are fighting the separatists.
Authorities in the Rostov region, where the refugee camp is located, say there are nearly 4,000 refugees in the region and that the number continues to grow.
Putin, marking #Russia Day: "Crimea's accession occurred peacefully, upon the will of people and in accordance with the international law."
