Russia and Ukraine traded attacks that killed at least four people Saturday, officials said, ahead of US-Ukraine talks on ways to end Russia's invasion of its neighbour. A man and a woman were killed and six people wounded, including two children, when a Russian drone hit a house in the Ukrainian city of Zaporizhzhia, regional head Ivan Fedorov said. Russian strikes also knocked out power across much of the northern Ukrainian region of Chernihiv, according to local officials. In Russia, two women were killed and another wounded by Ukrainian shelling of the Belgorod border region, Gov. Vyacheslav Gladkov said. The attacks came ahead of US-Ukraine talks in Miami that US Special Envoy Steve Witkoff said on X were "constructive." He said the meetings, which included US President Donald Trump's son-in-law Jared Kushner, were "part of ongoing mediation efforts, with discussions focused on narrowing and resolving remaining items to move closer to a comprehensive peace agreement."
