On the night of Monday, July 21, several regions of Russia were under a “Drone Threat” alert. For example, in Chuvashia and other areas. However, the restrictions were lifted by around 9:40 AM Moscow time. In Tatarstan, the drone threat alert lasted nearly 5 hours.

At the same time, Rosaviatsiya did not report any restrictions at the airports of Kazan and Nizhnekamsk, as well as other regions of the Volga Federal District. Despite this, several flights to and from Moscow were canceled at Kazan Airport. Preliminary reports suggest this was due to drone attacks on the Moscow region.

On the night of July 21, flight departures and arrivals were restricted at Moscow’s Sheremetyevo, Zhukovsky, and Domodedovo airports. Restrictions were also in place at Vnukovo Airport. These were lifted by around 4 AM. Flight operations at Nizhny Novgorod Airport remained prohibited until nearly 9 AM on Monday.

On the night of July 21, 74 Ukrainian drones were shot down over Russia, according to the country’s defense ministry. Most were destroyed over the Moscow region—23 in total, with 15 heading toward Moscow. Another 14 drones were downed over Kursk Oblast, 12 over Rostov Oblast, 10 each over Bryansk and Kaluga Oblasts, 4 over Tula Oblast, and 1 over Lipetsk Oblast.

Emergency services were deployed to the crash sites of the drones. No casualties were reported in Moscow. No details were provided about the aftermath of the drone attack in Kursk Oblast. The acting governor of Rostov Oblast confirmed no injuries in the region.

In the village of Kamennolomni, a drone attack damaged a dispatcher’s building at the railway station. A drone fragment reportedly hit the structure. As a result, trains were forced to reduce speed significantly, causing delays. Currently, over 50 trains are reported to be delayed.

“Russian Railways has assured that passengers on delayed trains will be provided with water, and if the delay exceeds four hours, meals will also be provided,” the statement noted.

No casualties were reported in Bryansk Oblast following the drone attack. The same was confirmed in Kaluga Oblast. The governor of Tula Oblast also reported no injuries. No details were provided about the impact of the drone attack in Lipetsk Oblast.

In many Russian regions, including Tatarstan, drone threat alerts are often accompanied by mobile internet slowdowns or outages. Due to this, a map of free Wi-Fi hotspots was activated in the republic. Even on July 21, complaints about slow internet speeds persisted in Tatarstan.
