“The overnight strikes hit Kyiv and the region around the capital, the Black Sea port Odesa and central Ukraine,” they said.

“At least one person was injured in the Kyiv region, with damage reported in five districts where more than a dozen houses were damaged,” regional governor Mykola Kalashnyk said on the Telegram messaging app.

Odesa governor Oleh Kiper wrote on Telegram that a nighttime drone attack on the energy infrastructure of the region caused fires that had been extinguished.

Russia attacks the Ukrainian energy system almost daily, striking thermal power plants and electrical substations.

Attacks on power stations, the energy transmission system and the gas sector are important elements of the full-scale invasion of Ukraine launched by Russia in February 2022.

Moscow says it is seeking to undermine Ukraine’s ability to fight.
