Three Ukrainian drones downed over Moscow: Russia DM

While one of the drones was shot down on the city's outskirts, two others were "suppressed by electronic warfare" and smashed into an office complex. 

One person was injured as a result of a blast that occurred in a Moscow City building after a drone attack, emergency services said.

The attack reported Sunday is the latest in a series of recent drone assaults -- including on the Kremlin and Russian towns near the border with Ukraine -- that Moscow has blamed on Kyiv.

The defence ministry called it an "attempted terrorist attack".

The capital's Vnukovo airport was closed for arrivals and departures due to the incident.
