At least three people have been killed in Ukrainian drone strikes targeting the Moscow region overnight, Russian authorities said on Sunday.
At least four people were injured, and several residential buildings were damaged and caught fire, while infrastructure sites were also attacked, Governor Andrei Vorobyov wrote on Telegram.
Moscow Mayor Sergei Sobyanin said more than 120 drones had been intercepted within 24 hours, with at least 12 people injured in the Russian capital, most of them workers near an oil refinery.
Several buildings were damaged, he wrote on Telegram.
The Russian Defence Ministry reported a total of 556 of Ukrainian drones that had been downed across the country overnight, according to state news agency TASS.
Ukraine also attacked the Russian-occupied Black Sea peninsula of Crimea overnight, damaging several apartment blocks in the capital Sevastopol, according to local authorities.
Debris from a downed drone struck a high-voltage power line, causing power cuts, Sevastopol Governor Mikhail Razvozhayev wrote on Telegram. However, the city’s power station was not hit, he said.
A total of 25 drones were shot down over the city and the Black Sea, according to Razvozhayev.
It was not possible to independently verify the claims.
Russia annexed Crimea in 2014, though it is still recognized internationally as Ukrainian territory.
The Ukrainian attacks came after Russia launched one of its heaviest and longest air assaults on Ukrainian targets earlier this week, with 24 killed in a strike on an apartment block in Kiev alone.
