Russia launched its first major bombardment of Ukraine since last month's deadly strike on Kyiv, killing at least four people overnight Sunday in a wave of drones and missiles that hit the capital hardest.

Tymur Tkachenko, head of the Kyiv City Administration, confirmed Sunday's casualties via Telegram and said 10 others were wounded in the attack that targeted civilian areas across the city. A 12-year-old girl was among the dead. Thick black smoke could be seen rising from a blast near the city center.

"The Russians have restarted the child death counter," Tkachenko wrote on Telegram.

Russia fired a total of 595 exploding drones and decoys and 48 missiles, Ukraine's air force said Sunday. Of those, air defenses shot down or jammed 566 drones and 45 missiles.

Besides Kyiv, Ukrainian President Volodymyr Zelenskyy said the bombardment targeted the regions of Zaporizhzhia, Khmelnytskyi, Sumy, Mykolaiv, Chernihiv, and Odesa.
