KYIV, Ukraine (AP) — The number of Russian troops killed or wounded in Ukraine has topped 1 million, military officials in Kyiv said Thursday, describing the huge price that Moscow has paid for its 3-year-old invasion.

It was already hard to imagine a breakthrough emerging from the direct talks between Russia and Ukraine set to be renewed in Istanbul on Monday.

Russian negotiators told the Ukrainian delegation directly that their so-called "peace memorandum" is an ultimatum Kyiv cannot accept, President Volodymyr Zelensky said in an interview with Hungarian news outlet Valasz Online published on June 10.

Russia launched 479 drones at Ukraine in the war’s biggest overnight drone bombardment, the Ukrainian air force said.
