Hundreds of drones targeting Moscow and its surrounding region killed at least two people on Sept. 20.
The strikes also damaged a major oil refinery on the final day of Russia's parliamentary elections.
Moscow Mayor Sergei Sobyanin said air defenses intercepted more than 1,600 drones.
He noted 450 of these drones were aimed directly at the capital.
Sobyanin accused Ukraine of attempting to disrupt the tightly controlled three-day election.
The vote aims to consolidate President Vladimir Putin's 26-year grip on power.
Moscow regional Governor Andrey Vorobyov confirmed the deaths of a 44-year-old woman and an elderly man in two separate locations.
A drone crashed into a 21-story building and triggered a fire.
Authorities evacuated 400 people from the residential block.
The strikes damaged a facility at the Moscow Oil Refinery.
Emergency services rushed to the scene to contain the damage.
Kyiv stepped up its long-range drone campaign against Russian energy infrastructure in recent months.
The latest attack follows recent remarks by U.S. President Donald Trump.
Trump recently claimed Ukraine and Russia agreed to stop targeting each other's energy facilities.
Russians began voting on Sept. 18 in the first parliamentary election since the start of the 2022 conflict.
Only parties supporting Putin and the Kremlin's military campaign registered to run.
