A Ukrainian drone attack on October 23 forced the suspension of civilian flights at all four of Moscow's major airports and reportedly struck a semiconductor plant in the city of Oryol, according to Russian authorities and open-source analysis.

Russian civil aviation authority Rosaviatsiya announced restrictions on arriving and departing flights at Sheremetyevo, Domodedovo, Vnukovo, and Zhukovsky airports at 2:05 p.m. local time on October 23. At Sheremetyevo, Moscow's largest airport, an air alert was sounded and waiting passengers were advised to take shelter. Photos later emerged on social media that allegedly showed debris from a downed drone on the tarmac, though the Kyiv Independent could not independently verify the images.

According to Moscow Mayor Sergey Sobyanin, 17 drones were shot down while heading toward the city on the afternoon of October 23. Open-source flight tracker FlightRadar24 reported 85 cancelled flights and a further 229 delayed at Sheremetyevo over the day. The all-clear was later sounded at Sheremetyevo, Russian state news agency TASS reported at5 p.m. local time.

An evacuation was also reported at the IQ-Quarter skyscraper in the Moscow City business district, which houses offices of several Russian government ministries including the Digital Development Ministry, Economic Development Ministry, and Industry and Trade Ministry. TASS later reported, citing emergency services, that the alarm had been false.

Meanwhile, explosions were reported in the Russian city of Oryol, approximately 350 kilometres (217 miles) southwest of Moscow, where a local industrial facility was targeted in a missile strike. Oryol Oblast Governor Andrey Klychkov confirmed that an enterprise had been targeted, while independent Russian media outlet ASTRA, citing its open-source intelligence analysis, identified the facility as the Proton plant. The plant manufactures semiconductor devices, LEDs and electronic components for industrial and specialised equipment that could be used in Russian weapons systems. Local residents reported hearing at least four explosions, ASTRA said.

Ukraine had not commented on the reported attack as of the time of publication.

As Ukrainian long-range drones have reached deeper into Russian territory, temporary airport closures across Russia have become increasingly common during Moscow's full-scale war against Ukraine. On September1, President Volodymyr Zelensky warned airlines, insurers and foreign governments that Russian airspace "will be de facto closed" because of Ukrainian drones. "Today we want to warn every airline that uses Russian airspace, every insurer, everyone who still uses key Russian airports — Russian skies are becoming completely dangerous," he said in an address posted to Telegram. "Although the Russian authorities do not report this as it should, the Russian sky will de facto be closed." Russian President Vladimir Putin responded by accusing Kyiv of "state terrorism," despite Russia's six days of attacks on Kyiv.

Analysis

Why This Matters

Civil aviation in Moscow is directly disrupted, with hundreds of flights cancelled or delayed, affecting passengers and airlines.
The reported strike on a semiconductor plant highlights Ukraine's ability to target military-relevant infrastructure deep inside Russia.
The attack signals an escalation in the war's reach, with potential implications for international air travel over Russian airspace and insurance markets.

Background

Since the start of Russia's full-scale invasion of Ukraine in February2022, Ukraine has increasingly deployed long-range drones to strike military and industrial targets inside Russia. Moscow has repeatedly accused Ukraine of targeting civilian infrastructure, while Kyiv frames its strikes as legitimate attacks on military assets. Temporary airport closures have become routine as drones approach the capital.

Key Perspectives

Russian authorities: Report the downing of17 drones and confirm the Oryol plant was targeted, but provide few details on damage. Mayor Sobyanin's account is the primary official narrative. Ukrainian government: Has not commented on the October23 attack. President Zelensky previously argued that Russian airspace is dangerous due to Ukrainian drones, calling on airlines and insurers to take note. Independent observers: Flight data and open-source analysis corroborate the airport disruption and identify the Oryol facility as a semiconductor maker with potential military applications, though independent verification of the strike itself remains limited.

What to Watch

Whether similar drone attacks continue over Moscow, leading to more prolonged airport closures.
Any official Ukrainian acknowledgment or denial of the Oryol strike.
Reactions from international aviation bodies and insurers regarding risk assessments for flights to Russian airports.
