More than 3,000 North Korean soldiers fighting with Russian forces in Kursk Oblast have been killed or injured, Zelenskyy said on Monday. Seoul earlier warned of North Korea's plans to deploy more troops and weapons.

Russia says five people have been killed in a Ukrainian strike in the western Kursk region. Ukrainian officials reported earlier that Moscow had launched a fresh missile attack on Kyiv, damaging a building hosting several embassies.

Six people, including one child, were killed on Friday in a Ukrainian missile attack on the town of Rylsk in Russia's Kursk region, the acting governor, Alexander Khinshtein, said.
