Russian strikes across Ukraine killed three people and wounded at least four others, Ukrainian officials said Sunday.
Moscow has fired hundreds of drones on its neighbor almost nightly since its 2022 invasion, while Ukraine has carried out regular attacks on Russian energy and military targets.
In the northeastern Ukraine border region of Sumy, one Russian drone attack killed two civilians, according to the head of Sumy's regional military administration.
"The enemy struck civilians in the territory of Bilopillia community -- near one of the settlements, less than five km from the state border with the Russian Federation," Oleg Grygorov said in a post on Telegram.
He said two men aged 48 and 72 were killed, AFP reported.
Drone and artillery attacks in the central-eastern city of Dnipro, meanwhile, killed one person and wounded four more, the region's military administration head Oleksandr Ganzha said.
Ganzha in a Telegram post said private homes and vehicles were damaged.
Earlier Sunday, the Moscow-installed governor of Sevastopol in Russian-annexed Crimea said a man was killed in a vehicle during a Ukrainian drone attack that damaged several homes and a dance school in different neighborhoods of the port city.
The governor said Russia shot down 43 drones in the attack.
On Saturday, Ukrainian authorities said at least eight people were killed in Dnipro, which was hit by waves of Russian strikes for 20 hours straight.
