A Russian attack on Ukraine's northeastern region of Kharkiv late last night killed three civilians and wounded one more, regional police said.
Russian forces used an aerial bomb to carry out the attack, which damaged houses and a medical facility, the police said on the Telegram messenger app.
Kharkiv, Ukraine's second largest city, and the surrounding region have been subject to constant Russian strikes since Moscow launched a full-scale invasion in February 2022.
The Regional Governor of Kharkiv said earlier that at least 15 people were wounded.
Also writing on the Telegram messaging app, Oleh Syniehubov said the attack damaged two residential buildings and windows of an infrastructure facility, two supermarkets, a café, 21 kiosks and a shopping centre.
There were four interior ministry employees among those injured in Kharkiv, the governor said.

He said Russian forces had badly damaged a five-storey apartment building in Kivsharivka, a small town near Kupiansk, east of Kharkiv.
"The Russian armed forces carried out massive air strikes on Kharkiv and its suburbs," prosecutors told AFP journalists at the scene.
Emergency services are assessing the damage.
Ukraine has for months been urging Western allies to supply more air defence systems to fend off Russian attacks.
Kyiv said it had downed 50 Iranian-designed Russian drones in nine regions overnight, including over the capital Kyiv.
It also said a Russian cruise missile had struck the Dnipropetrovsk region.
