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.

All of the Ukrainian troops need treatment, Ukraine's President Volodymyr Zelenskiy said in a message on the Telegram messaging app.

Russia launched one of its largest air strikes on Kyiv in over three years of war and struck a maternity ward in the southern city of Odesa, officials said.
