The United States and Europe on Tuesday planned to impose new sanctions on Moscow over the killings of civilians in Ukraine, while Ukrainian President Volodymyr Zelensky warned that more deaths could be discovered in areas controlled by Russian invaders.

Russian forces withdrew from towns north of the capital Kyiv last week as their offensive shifted to southern and eastern Ukraine. Ukrainian forces have regained control of towns devastated by nearly six weeks of war, including Bucha, where the corpses of civilians littered the streets.

And since yesterday, Monday, European countries began expelling Russian diplomats against the background of the atrocities, as Germany decided to expel about 40 diplomats, France about 35, and Spain 25, which prompted the Kremlin to denounce the European "narrowness of vision", vowing to respond to these measures.

Russia has denied any accusations of killing civilians in the areas it has withdrawn from in Kyiv, and said it would present "practical evidence" at a meeting of the UN Security Council on Tuesday that its forces were not involved.
