"Kyiv then suffered one of the biggest aerial assaults of the war overnight on Saturday.

Videos posted on social media showed explosions lighting up the sky throughout the night, and many Kyiv residents reported blasts rocking the city as numerous civilian targets were hit.

Russia employed dozens of ballistic and cruise missiles and hundreds of drones to hit the capital, as well as firing a hypersonic, nuclear-capable Oreshnik missile on the area of Bila Tserkva, 90km south of Kyiv.

Non-military targets such as the Chernobyl Museum in Kyiv's historic district and the National Art Museum of Ukraine were damaged or destroyed. A shopping centre, a market and several residential buildings in the area of Lukanivka were also destroyed.

On Monday evening, Russian Foreign Minister Sergei Lavrov urged US Secretary of State Marco Rubio to evacuate American diplomats from Kyiv in a phone call, Russia's foreign ministry said."
