All four international airports around Moscow temporarily suspended flights Tuesday as Russian forces intercepted more than 100 Ukrainian drones fired at almost a dozen Russian regions, the Defense Ministry in Moscow said.

Ukraine attacked Moscow with drones for a third day on Wednesday forcing most of the Russian capital's airports to close just as Chinese President Xi Jinping was due to arrive to mark the victory over Nazi Germany in World War Two.

Moscow's four international airports closed for hours overnight following an attack by Ukrainian drones on the capital that spread to other Russian cities and airports. Russian forces shot down 105 Ukrainian drones overnight, the Russian defense ministry told local news agencies.
