Russian forces downed 19 Ukrainian drones overnight – 16 over the southern Rostov region and the remainder over the Belgorod and Bryansk regions – Russia's Ministry of Defence said on Sunday. Blasts were heard in Kyiv early on Sunday and smoke was seen rising from above residential buildings after a suspected Russian drone attack on Ukraine's capital. The attack comes after Kyiv's Mayor Vitali Klitschko said on the Telegram channel that Ukraine's air defence units were trying to repel a Russian air attack on the city, ordering people to stay in shelters. Ukrainian forces are restraining one of Russia's "most powerful offensives" since the start of Moscow's full-scale invasion in 2022, Ukraine's top military commander, General Oleksandr Syrskii, has said. Russia troops have taken two more settlements along the Donbas frontline – Kurakhivka and Pershotravneve – Russian news agencies reported on Saturday, citing the country's Defence Ministry.

The number of people injured in a Russian air attack on Kharkiv, Ukraine's second-biggest city, rose to 21, including an eight-year-old child. Ukrainian President Volodymyr Zelenskyy said Russia used glide bombs to target "an ordinary residential building". Regional Governor Oleh Syniehubov said people were sleeping when the attack happened and two of the injured were in critical condition. Kharkiv's city council said 18 buildings were damaged in the attack. In Ukraine's eastern Donetsk region, a Russian air attack struck homes in the city of Sloviansk, trapping one woman under the rubble and injuring two of her neighbours, regional prosecutors said.
