An explosion hit the 75th Arsenal, a Russian army plant in Serpukhov south of Moscow, overnight on 22 October, Russian Telegram channel Astra reported. Russian officials also claimed drone attacks on the Moscow region, Tula, and Lipetsk that night.

As Russia presses its full-scale invasion, Ukraine’s long-range drones and missiles keep hitting military plants and refineries deep inside Russia. Ukrainian outlet Militarnyi says this plant specializes in repairing Buk and S-300 air defense systems. Astra describes it more broadly, as making weapons and ammunition and repairing military equipment. If Militarnyi is right, the blast hit a site that fixes Russian air defenses. It came the night Moscow’s mayor credited air defenses with stopping hundreds of drones.

Blast at the arsenal

An Astra OSINT analyst placed the explosion inside the site from a video, the channel said. Residents claimed in local chats that blasts followed passing drones, then at least three missiles. Astra did not confirm the missile count. Serpukhov lies about 99 km south of Moscow. Ukraine has sanctioned the plant, and the US Treasury has listed it too. As of the morning of 22 October, no Russian official had confirmed the blast.

630 drones, by Moscow’s count

Moscow Mayor Sergei Sobyanin claimed that 630 drones flew toward the Moscow region from 20:30 on 21 October to 04:00 on 22 October. He claimed most were destroyed far out and 163 were neutralized on approach to Moscow. Two people were injured in Voronovo, in New Moscow, he stated.

Tula Oblast Governor Dmitry Milyaev claimed air defenses downed 70 Ukrainian drones over his region. Private homes were damaged in Tula and the Zaoksky district, he stated.

Lipetsk governor claims homes and a clinic damaged

Earlier in the night, Ukrainian monitoring channel Exilenova+ posted footage of commotion in Lipetsk after explosions. Lipetsk Oblast Governor Igor Artamonov claimed a drone strike damaged homes, apartment blocks, and a closed polyclinic. A man born in 2001 was injured and hospitalized, Artamonov claimed.

In May, Ukrainian intelligence said Russia was deploying more regiments against strike drones. In September, Ukrainian units hit more Russian air defense systems and radars than in any month since 2024, Ukraine’s Defense Ministry said. Analyst Oleksandr Kovalenko counted 76 destroyed in September with days of the month still to go and argued Russia cannot replace such losses. If Militarnyi’s description holds, losing repair capacity would deepen that gap.

Ukrainian forces struck a weapons plant in Serpukhov, Moscow Oblast, overnight on Oct. 22, monitoring channels reported.

Norway has put into force a new round of sanctions against Russia that hits banks, listed oil refineries, ports, airports, and suppliers of Russia’s military industry, the Norwegian Foreign Ministry announced. The rules mirror the EU’s 21st sanctions package, which Brussels adopted in July.

The EU’s 22nd package, adopted on 12 October, is principally a list of names, while the 21st brought significant new measures, lawyers noted. Among them are new tools against the shadow fleet, the tankers with murky ownership that Russia uses to move oil around sanctions. That fleet also sails along Norway’s coast, and a new Norwegian Coastal Administration report found that it poses a growing threat to security and the environment there.

Banks, refineries, and Sheremetyevo

Norway is not an EU member, but it has joined every EU sanctions package against Russia, with a few exceptions and national adjustments. Oslo backed this one politically on 11 August, and the rules took effect on 21 October. Part of the package was already in force. It placed travel restrictions and asset freezes on 48 people and asset freezes on 168 entities, and it listed 41 shadow fleet vessels on 14 August.

Norway’s transaction ban now covers 33 more Russian credit and financial institutions. A separate ban covers 22 more abroad, including in India, Mongolia, Nigeria, and the UAE.

Another transaction ban reaches listed refineries in Russia and third countries that process Russian oil or help dodge sanctions. A Georgian refinery joins that list on 25 January 2027. The same ban adds two Russian ports and four Russian airports, including Moscow’s Sheremetyevo.

Drone gear and the shadow fleet

Export curbs on dual-use goods now cover 51 new entities that back Russia’s military industry. Some are in China, including Hong Kong, and others are in India, Kazakhstan, Kyrgyzstan, Türkiye, and the UAE. The banned-exports list adds nickel and beryllium powder, along with drone gear such as jamming and interception systems, launchers, and servo motors.

Oslo can now also list ships that service sanctioned shadow fleet tankers or swap cargo with them at sea. Elsewhere in Europe, France’s navy and UK forces have boarded sanctioned shadow fleet tankers this year.

Temporary restrictions on aircraft arrivals and departures were imposed at 27 Russian airports, Deutsche Welle reported on 16 October, citing its own calculations based on reports from Russia’s Federal Air Transport Agency.

Ukrainian President Volodymyr Zelenskyy warned airlines on 1 September that “Russian airspace is becoming completely unsafe.” Overnight, most of the airspace over European Russia was closed.

By morning, more than 200 flights had been canceled or delayed at Moscow airports, Deutsche Welle reported, citing figures compiled by a Russian Telegram channel.

Тим часом у російських аеропортах – справжній апокаліпсис через нальоти дронів останніми днями.

Про це ниють росЗМІ. Було відмінено десятки рейсів, у терміналах – дуже багато людей. Пасажири скаржаться на задуху, дикі черги до туалетів та повну невідомість. pic.twitter.com/ZlXxY5c2mq

The list included airports in the capital. All four Moscow airports temporarily suspended arrivals and departures, the Russian outlet Astra reported on 16 October. Russian authorities said they had shot down dozens of drones, while flights were delayed and diverted to alternate airfields, according to the report.

Massive drone attack on Russia: 644 UAVs in one night, 94 shot down near Moscow

The temporary airport shutdowns were likely a consequence of a massive drone attack on Russia. From 8:00 p.m. on 15 October to 8:00 a.m. on 16 October, Russian air defenses allegedly intercepted and destroyed 644 Ukrainian unmanned aerial vehicles across 26 Russian regions, occupied Crimea, and the Black Sea, according to Russia’s Defense Ministry.

According to the list of regions published by the Russian Defense Ministry, the drone attacks covered a vast area of Russia, from regions bordering Ukraine to the Moscow region, the Volga region, the country’s northwest and southern regions, as well as occupied Crimea and the Black Sea.

Russian air defenses shot down a total of 94 drones approaching Moscow over the evening of 15 October and overnight, according to calculations by the Russian outlet RBC Radio, citing statements by Moscow Mayor Sergey Sobyanin.

In the Kaluga region, air defenses destroyed 27 drones over the evening and night, the regional governor reported. At 9:27 a.m., he updated the figures, saying another 48 UAVs had been shot down overnight, bringing the total to 75. According to preliminary information, there were no casualties or infrastructure damage.

In the Tula region, air defenses allegedly destroyed a total of 32 Ukrainian drones. There were no casualties, according to regional Governor Dmitry Milyaev in his Telegram channel.

In the Vladimir region in western Russia, authorities repelled drone attacks overnight. In the city of Vladimir, a drone attempted to attack a heating infrastructure facility, but the attack was stopped, Vladimir Region Governor Alexander Avdeyev reported. Minor damage was reported, but there was no information about casualties.

Ukraine has not yet commented on its involvement in the attacks.

The practical consequences of canceled Russian flights

Passengers on flight SU6312 from Kaliningrad to Moscow were unable to land in Moscow because of airspace closure, so the aircraft was diverted to Nizhny Novgorod, Terravia reported. After landing, passengers remained on board for about two hours before being allowed to disembark at 3:30 a.m. Instead of continuing their journey to Moscow by air, they were supposed to be transported by bus, with the trip expected to take about seven hours, the outlet reported.

Passengers were not provided with food or drinks, and one woman could not find a seat on the bus, so she purchased a ticket for an early-morning train herself.

Since the beginning of the year, all four Moscow airports have been completely shut down simultaneously at least 19 times, the Russian outlet Agentstvo reported. During the first 14 days of October, the restrictions lasted 101 hours and 38 minutes, compared with 46 hours and 33 minutes in September, according to the report.
