At least four people were killed and seven wounded in Russia on Monday when Ukrainian drone strikes targeted the Moscow region, local officials said, as Kyiv escalated its attacks in response to Kremlin barrages.
Ukraine has been striking Russia, particularly energy targets, which Kyiv says is fair retribution for Moscow's more than four years of attacks on its territory.
"In the settlement of Pionersky in Istra, three people were killed and three more wounded as a result of a drone falling," Moscow Region Gov. Andrey Vorobyov posted on Telegram.
Two more people had been wounded in another part of the region, he added.
Air defenses shot down 81 drones over the region, Vorobyov said.
