According to the defence ministry, two drones were shot down in the Moscow region’s Mozhaisk and Khimki districts.

No casualties have been reported, and it is unclear who carried out the attack.

An official from the Russian government described it as “another terrorist attack by the Kyiv regime”.

It is rare for Ukraine to comment on who is behind attacks inside Russian territory.

On Wednesday, all flights to and from Moscow’s airports were suspended early, but later resumed operations. In recent days, flight suspension measures have been taken repeatedly.

The AFP news agency reported that it was the sixth consecutive night of aerial attacks on Russia’s capital region.

According to the defence ministry, electronic warfare systems suppressed the drone that hit the Moscow City complex. According to the report, the plane lost control and collided with the building.

Several windows were smashed in two five-story buildings opposite, and emergency services were inspecting the area, the mayor said.

According to the US State Department, Washington does not encourage drone attacks in Russia.

According to US officials, Ukraine should decide how to defend itself, and Russia could withdraw from its neighbor at any time.

According to officials, three elderly people were also killed by Russian shelling near Lyman, a city in eastern Ukraine.

• Drone attacks in Russia: what do we know?

Recent months have seen an increase in reports of drone strikes inside Russia.

Two drones were downed over the Moscow area on Tuesday, and two more were intercepted over the Bryansk region near the Ukrainian border.

Sobyanin said Russian air defences shot down two drones west of the capital in Krasnogorsk and Chastsy. There were no injuries reported.

Also on Tuesday, a Russian warplane destroyed a Ukrainian reconnaissance boat near Russian gas production facilities in the Black Sea.

The Ukrainian government did not claim responsibility for any drone incursions on Tuesday, but President Volodymyr Zelensky said previously that attacks on Russian territory are “inevitable, natural, and absolutely fair”.
