Russian officials said Thursday the country’s air defenses shot down a Ukrainian drone flying toward Moscow.

The Russian defense ministry said the drone was destroyed over the Voskresensky district.

Sergei Sobyanin, Moscow’s mayor, said on Telegram there were no reports of casualties or damage.

Ukraine on Wednesday launched a wave of drone attacks aimed at six Russian regions, including hitting an airport near Russia’s border with Estonia and Latvia.  That drone ignited a huge blaze and damaged four Il-76 military transport planes, which can carry heavy machinery and troops, the Russian news agency Tass reported, quoting emergency officials.

Kremlin spokesperson Dmitry Peskov said the Russian military would undoubtedly analyze “how this was done in order to take appropriate measures to prevent these situations in the future.”

Russia’s Foreign Ministry spokesperson Maria Zakharova said Ukraine was relying on foreign help because the drones “simply would not be able to fly such a distance without carefully researched information from Western satellites.”

Meanwhile, Moscow’s forces hit Kyiv with drones and missiles with what Ukrainian officials described as a “massive, combined attack” that killed two people with falling debris.

Sergei Popko, the head of Kyiv’s military administration, described Russia’s attack on the Ukrainian capital as the biggest since the spring, even as Ukraine’s air defenses shot down more than 20 drones and missiles.
