Russia launched drones, airstrikes and shelling at Ukraine on Sunday night, targeting cities such as Odesa in the south and Dnipro in the southeast, killing one person and injuring more than 30, Ukrainian officials said on Monday.
Drones hit residential buildings, a school and a kindergarten in the major Black Sea export port of Odesa, Serhiy Lysak, the head of the local military administration, said on messaging app Telegram.
An 11-year-old boy and a 59-year-old man were injured in the attack, he added.
Russia hit the southeastern Ukrainian city of Dnipro with missiles in a separate attack, injuring 18, among them two children, a girl of two and a boy of 10, regional governor Oleksandr Hanzha said on Telegram.
In the southeastern region of Zaporizhzhia three people were injured following the overnight attacks, the regional governor, Ivan Fedorov, added on Telegram.
Attacks in the southern region of Kherson killed one person and injured nine, regional governor Oleksandr Prokudin said on Telegram.
In total, Ukraine's air force reported on Monday that 524 drones and 22 missiles were launched overnight, with air defence units shooting down or neutralising 503 drones and four missiles.
In Russia, drones were downed overnight over regions such as Rostov and Belgorod in the south, the Interfax news agency said, citing the defence ministry.
At least four people died over the weekend, three of them in the Moscow region, after Ukraine launched its biggest overnight drone attack on the Russian capital in more than a year, officials said on Sunday.
Reuters could not independently verify battlefield reports. Both sides deny deliberately targeting civilians.
