In Ukraine, three people were killed in the town of Balakliya, Kharkiv region, in an overnight Russian drone attack, the country’s state emergencies service DSNS said.
It said private residential houses were targeted, with fires reported in two buildings.
Kharkiv regional head Oleh Synehubov later said that another two people were killed when drones attacked the train station in Lozova. Another eight people were injured.
Later on Thursday, five people were killed in Russian strikes on the central Dnipropetrovsk region, local officials said.
In the south, the entire city of Kherson lost electricity after a “critical infrastructure facility” was hit overnight, regional head Oleksandr Prokudin said.
Internet monitoring group NetBlocks told BBC Verify it had observed “deep disruption” to connectivity in the Kherson region. According to telemetry data, internet connectivity fell to about 31% at its lowest overnight. The situation was ongoing and connectivity was about 69% as of 12:00 GMT.
NetBlocks’ head of research Isik Mater said connectivity did not fall to zero in part due to the use of “generators and backup supplies” in Kherson.
In Ukraine’s Black Sea port of Odesa, one person was killed when Russia hit two dry cargo ships.
Meanwhile, the Russian military said its forces intercepted or shot down 605 Ukrainian drones overnight over a number of regions.
In its latest operational update, the military said it struck Ukraine’s fuel, energy and transport facilities, as well as drone storage sites.
