Russian airports in Nizhnekamsk, Izhevsk, and Perm have temporarily suspended all flight arrivals and departures starting at 10:05 AM local time due to safety measures for civil flights, as announced by the Russian aviation authority, Rosaviatsia. The reason for the suspension has not been clarified, but past occurrences suggest it may be linked to threats from Ukrainian drones in the area. These cities are located east of Moscow.
