It began back in May this year when a startling video emerged showing something that nobody

expected to see in Moscow.

It would be a pretty remarkable breach of Russian air defenses for a drone like that to fly

all the way across the country and hit the Kremlin.

Two drones were seen flying over the Kremlin, the headquarters of the Russian President.

In minutes, there was a small explosion, nobody was injured.

And then, a few weeks later, there was another drone attack in Moscow.

Russian TV says this is the moment that Moscow came under attack from early morning, people

in and around the Russian capital reported hearing explosions.

And yesterday Moscow awoke to a fresh round of drone strikes, one narrowly missing Russia's

defence ministry.

Russia has accused Ukraine of launching a drone attack on Moscow.

Russia's defence ministry says two drones hit non-residential buildings with one crashing

close to its headquarters in the city centre.

No casualties have been reported.

Although the drone attacks on Moscow feel new, over the past year we have seen Russia being

directly targeted in other ways too, through assassinations on Russian territory and damage

to the country's infrastructure.

Drone sitting in the Kremlin, then blowing up the Kirch bridge linking Russia to Crimea,
