At least one person was killed as Ukraine faced fresh Russian drone, artillery and missile strikes overnight and on Wednesday morning, officials said.
A dawn airstrike on the city of Beryslav in Ukraine's southern Kherson region killed a 42-year-old man, governor Oleksandr Prokudin said Wednesday in a post on social media.
The attack destroyed a residential building, inflicting fatal injuries on the owner, Ukrainian emergency services said.
Some 16 were injured in the western Khmelnytsky region from falling debris after Ukrainian air defences shot down Russian drones, Ukraine's interior minister Igor Klymenko said.
Power lines damaged near nuclear plant
Ukraine's energy ministry also said Wednesday Russia had struck near a nuclear power plant in the region, blowing out windows in nearby buildings and damaging power lines.
President Volodymyr Zelensky said Ukraine was braced for more Russian attacks on the country's energy facilities over the winter.
"This year we will not only defend ourselves, but also respond," he said in a post on social media.
Ukraine's air force said it shot down 11 Iranian-made Shahed drones launched by Russia overnight.
Russia has used hundreds of the self-detonating drones against Ukraine in attempted overnight attacks in recent months.
Shelling was also reported in several regions close to the front lines.
In the northeastern Kharkiv region, artillery fire on Tuesday killed two civilians, governor Oleg Sinegubov said.
Zelensky also said Ukrainian forces were engaged in "heavy, tough battles" around the cities of Kupyansk and Avdiivka.
Avdiivka, in the eastern Donetsk region, has been the focus of heavy Russian attacks in recent weeks.
The industrial city has become a byword for Ukrainian resistance and has, so far, been able to repel the columns of armoured vehicles and troops Russia has sent.
"Our soldiers are holding their ground," Zelensky said Wednesday.
Separately, Russian authorities Wednesday opened a terrorism investigation after they said a Russian soldier was killed in a car bombing in Berdyansk -- a southern Ukrainian city seized by Russian forces at start of the war.
Russia's Investigative Committee said an unknown person planted an improvised explosive under a parked car on Monday evening which detonated when the soldier got into the vehicle.
