Ukraine targeted the Russian capital on Tuesday in its biggest drone attack so far, killing at least one and wrecking dozens of homes in the Moscow region and forcing around 50 flights to be diverted from airports around Moscow.
Russia, the world's biggest nuclear power, said it had destroyed at least 20 Ukrainian attack drones as they swarmed over the Moscow region, which has a population of more than 21 million, and 124 more over eight other regions.
At least one person was killed near Moscow, Russian authorities said. Three of Moscow's four airports were closed for more than six hours and almost 50 flights were diverted.
Kremlin spokesman Dmitry Peskov told reporters that the drone attack was another reminder of the real nature of Ukraine's political leadership, which he said was made up of Russia's enemies.
"There is no way that night time strikes on residential neighbourhoods can be associated with military action," said Peskov.
