A night-time Ukrainian drone attack on Moscow damaged two office blocks, the mayor said early Sunday, as one of the Russian capital's four airports was reportedly closed to traffic.

"Ukrainian drones attacked tonight. Facades of two city office towers were slightly damaged. There are no victims or injured," Moscow Mayor Sergei Sobyanin posted on Telegram.

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 capital's Vnukovo airport is closed for departures and arrivals, flights are redirected to other airports," state news agency TASS reported.

Earlier this month, a volley of drone attacks briefly disrupted air traffic at the same airport, to the southwest of Moscow.

Russia's defence ministry said three Ukrainian drones were downed during the attacks on Moscow.

The drone strikes come several weeks into a Ukrainian counter-offensive to claw back territory captured by Russia since large-scale hostilities erupted in February 2022.

On Friday Russia said it had intercepted two Ukrainian missiles over its southern Rostov region bordering Ukraine, with at least 16 people wounded by debris falling on the city of Taganrog.

Regions bordering Ukraine have seen regular drone strikes and shelling since Moscow launched its military campaign in February last year, but have hardly ever been targeted by missiles. (AFP)
