The Russian assaults came days after a US official said the US would support Ukraine launching deep strikes inside Russian territory.
“Polish and allied aircraft are operating in our airspace, while ground-based air defence and radar reconnaissance systems have been brought to the highest state of readiness,” Poland’s operational command said in a post on X.
At 05:10 (02:10 GMT), all of Ukraine was under air raid alerts following Ukrainian Air Force warnings of Russian missile and drone attacks.
Russia continues to focus its attacks on Ukraine’s energy infrastructure as winter approaches.
Kyiv’s energy ministry said overnight attacks caused damage in Zaporizhzhia, Chernihiv and Sumy.
In Zaporizhzhia, Russia’s overnight attack left “more than 73,000 consumers… without electricity” after a power plant was struck, according to Ivan Fedorov, the regional governor.
A woman was killed and several others injured in the region.
A 16-year-old girl was among those receiving medical assistance, Fedorov added, posting photos apparently showing a partly destroyed multi-storey block and a burnt-out car from the site of the attack.
Emergency outages were implemented in Chernihiv and Sumy, the energy ministry added.
Lviv’s mayor Andriy Sadovyi said part of the city – 70 km (43 miles) from the border with Poland – had no power, adding that city’s air defence systems were engaged heavily in repelling first a drone and then a Russian missile attack.
Ukraine’s air force said it recorded direct hits by eight Russian missiles and 57 drones at 20 locations across the country, as well as fragments from downed weapons at six locations.
It said 478 missiles and drones were downed and six did not reach their targets.
