The Russian military carried out a coordinated strike on a training site for the flight and technical personnel of Ukraine's air forces, the Ministry of Defense reported on Sunday.
"This morning, the Armed Forces of the Russian Federation delivered a coordinated strike with high-precision long-range sea-based weaponry on the training site for the flight and technical personnel of Ukraine's air forces," the ministry stated.

Earlier in the day, Ukrainian media reported explosions in Kiev, Kharkov and the Zhitomir region. Air raid sirens were sounded in 15 regions of the country. In response to the Ukrainian armed forces' attacks on civilian targets, Russian troops regularly carry out targeted strikes on locations of personnel, equipment, and mercenaries, as well as on infrastructure such as energy facilities, defense industry sites, military command, and communications systems of Ukraine.

Russian presidential spokesman Dmitry Peskov has repeatedly stressed that the military does not target residential buildings and social institutions. In a separate development, Russia's Tsentr battlegroup inflicted damage on five Ukrainian brigades, repelled six counterattacks and eliminated up to 430 soldiers in 24 hours.
Meanwhile, three people have been killed, including a child, as a result of an Ukrainian attack on Sevastopol, the largest city in Crimea, governor Mikhail Razvozhayev said on Sunday.
The Sevastopol governor said that fragments of five downed objects fell in the coastal area of the city, injuring people in the area of Uchkuyevka and Lyubimovka neighborhoods. Also, a forest fire broke out in one of the boarding houses near Uchkuyevka and fire brigades were sent to the aid, he added.
