Russian attacks caused a fire at an industrial site in Kremenchuk in Poltava Oblast, Governor Filip Pronin reported on Jan. 27.
Explosions were also reported in Kharkiv around 8 p.m., Kharkiv Mayor Ihor Terekhov reported, urging residents to take shelter.
Information about the number of victims was still being clarified at 8 p.m. local time, but first responders were reportedly sent to the site, Pronin said.
Attacks on Poltava Oblast have increased in November and December. Falling debris from a drone intercepted during a Dec. 20 attack on Poltava Oblast damaged a local residence without casualties.
Russian forces have regularly launched brutal attacks against Kharkiv, often targeting civilian areas, since the beginning of Russia’s full-scale invasion in February 2022.
Russia's latest mass missile attack on Jan. 23 killed at least 11 Kharkiv residents, including a child, and injured 70.
