Flight restrictions imposed on airports in four cities in Russia

Flight restrictions have been implemented at the airports of Kazan, Samara, Ulyanovsk, and Cheboksary, located in Russia's Tatarstan and surrounding regions. The acceptance and departure of flights to and from these airports have been temporarily suspended.

Authorities have not yet made an official statement regarding the reason for the restriction. Similar restrictions had previously been applied from time to time in various cities across Russia due to regional security reasons.
