A Russian missile and drone strike has hit the Kyiv region in Ukraine and killed at least four people. The regional administration head said at least 15 people were wounded. He said on Saturday that the attack hit four districts and damaged homes, schools, businesses and critical infrastructure. Russia’s Defense Ministry said the strikes targeted energy and industrial facilities linked to the Ukrainian military. Ukrainian drones meanwhile hit an oil refinery and port in Russia’s southern Krasnodar region. The U.S. has postponed planned peace talks this week, citing the war in the Middle East, and announced a 30-day waiver on Russian oil sanctions.
