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.

Since then, Russia and Ukraine have swapped dozens of prisoners of war, focusing on under-25s and the severely wounded and sick. There are hopes they could build into some of the biggest exchanges in the war that was triggered by Russia's 2022 invasion of Ukraine.

The second round of talks was even shorter than the first and didn’t address any substantive issues to ending the three-year conflict.
