At least one person was killed and flight travel was disrupted across Russia as Ukraine launched a second consecutive day of large-scale drone attacks on the country, Russian officials said early Thursday.

Authorities in the western Bryansk region said a civilian was killed and another injured in a “targeted strike” on Kamensky Khutor, a village near the border with northeastern Ukraine’s Chernihiv region.

In the neighboring Kursk region, a local official suffered hip and arm injuries from a drone strike, while authorities in the Tula region reported two civilians received minor wounds from air attacks that damaged the roof of an apartment building in the regional capital.

Moscow Mayor Sergei Sobyanin said Russian air defenses repelled more than 40 drones targeting the Russian capital overnight and Thursday morning, a day after around three dozen drones took aim at the city.
