At least three people were killed near Moscow after Ukraine targeted Russia with more than 500 drones overnight, Russian state news agency TASS reported Sunday, citing local and military officials.

The attack on Moscow is “the largest in over a year,” according to TASS, citing information released by the city’s mayor, and follows a huge wave of Russian strikes earlier in the week targeting Ukraine’s capital, Kyiv. Those attacks killed at least 25 people and injured dozens of others, according to Ukrainian authorities.

Overnight into Sunday, a woman was killed after a drone hit a private home in Khimki, a town to the northwest of the Russian capital, mayor Sergey Sobyanin said, adding that another person was trapped under the rubble.

Two men were killed in Mytishchi, to Moscow’s northeast, when drone debris fell on a house under construction, Sobyanin said, adding that a total of 12 people were injured in Moscow, including construction workers at an oil refinery.

Russia’s Defense Ministry said it intercepted 556 Ukrainian drones overnight, while Sobyanin said air defences shot down more than 120 drones heading for Moscow and its environs.
