Ukraine targeted Moscow early on Tuesday in what seemed its biggest drone attack of the war on the Russian capital, killing at least one person, sparking fires and suspending air and train transport in the region, authorities said.
"Today at 4 a.m. a massive drone attack began on Moscow and the Moscow region," Moscow Region Governor Andrei Vorobyov said in a post on the Telegram messaging app. "At the moment, one person is known to have died and three were injured."
Russia's air defense units destroyed 337 Ukrainian drones overnight, with 91 of them over the Moscow region, Russia's defense ministry said on Tuesday.
The ministry said in a post on its Telegram channel that 126 drones were destroyed over the Kursk region that borders Ukraine, while the rest of the drones were downed over eight other Russian regions.
Moscow and its surrounding region, with a population of at least 21 million, is one of the biggest metropolitan areas in Europe, alongside Istanbul.
Russia's aviation watchdog said flights were suspended at all four of Moscow's airports to ensure air safety after the attacks. Two other airports, in the Yaroslavl and Nizhny Novgorod regions, both east of Moscow, were also closed.
Vorobyov said that at least seven apartments were damaged and residents forced to evacuate in a multi-story building in the Ramenskoye district of the Moscow region, about 50 km (31 miles) southeast of the Kremlin.
Rail infrastructure at the train station in the Domodedovo district, about 35 km south of Moscow, was damaged as result of falling drone debris, RIA news agency reported.
Baza, a news Telegram channel that is close to Russia's security services, and other Russian news telegram channels posted videos of several residential fires around Moscow that they said were sparked by the attacks.
The strikes came as the United States is pushing for an end to the three-year war that Russia started with its invasion of Ukraine in February 2022. On Tuesday, US and Ukrainian teams are scheduled to meet for peace talks in Saudi Arabia.
Governors of Ryazan region, just southeast of the Moscow region, and the Belgorod region on border with Ukraine, also said that their regions were under drone attacks. Several settlements in the Belgorod region were left without power, the regional governor said.
Previous drone attacks on Moscow
A November drone attack on Moscow, the largest in the war at that point, led to the destruction of at least 34 drones. At least one civilian was killed and dozens of homes wrecked around the capital.
Kyiv has often said that its strikes inside Russia are aimed at destroying infrastructure key to Moscow's overall war efforts and are in response to Russia's continued bombing of Ukraine.
Both sides deny targeting civilians in the attacks, but thousands of them have died in the conflict so far, the vast majority of them Ukrainian.
