Russia: Officials temporarily restrict flight operations at multiple airports across southern Russia as of late Jan. 1

As of late Jan. 1, officials have temporarily restricted flight operations at multiple airports across southern Russia due to a possible drone threat. The measure covers airports in Kaluga, Saransk, Penza, and Saratov. Authorities did not provide a time frame for when services would resume.

Increased security is almost certain over the coming hours. Flight delays and cancellations are likely due to the temporary restrictions, and they may linger even after the measure is lifted as airline officials work through passenger backlogs.
