Nine people were killed and 23 injured in Ukrainian strikes on Russia over 24 hours, including eight deaths in Belgorod and one in Astrakhan, Russian officials said.
Four people were killed in Russian attacks on Ukraine — two in Sumy and two in Donetsk — while an overnight strike on Odesa damaged a civilian vessel and injured four more.
The latest exchanges followed what Russia called Ukraine's largest attack of the year, with 822 drones launched on Saturday night, including 600 aimed at Moscow, after which at least seven people were reported killed in Russia.
Kyiv has signaled the deep strikes will continue, saying repeated attacks have disabled seven of Wildberries' 10 biggest logistics centers and arguing such hubs support Russia's war effort.
Russia has also intensified bombardment across Ukraine, with Zelensky saying 13 regions were hit last week and Naftogaz reporting 13 attacks on its facilities in the past week.
