Zelensky said attacks on Russian territory were an “inevitable, natural and absolutely fair process” of the war between the two countries.
Russia’s defence ministry said three Ukrainian drones were downed yesterday, with two crashing into offices.
Vnukovo Airport, southwest of the city centre, was also briefly shut.
The drone attack in the early hours of yesterday is the latest that Moscow has blamed on Kyiv.
Ukraine rarely claims responsibility for attacks inside Russia.
