Kazakhstan's Qazaq Air has suspended flights for an unspecified period from the Central Asian nation's northwestern city of Aqtobe to the capital of Russia's Republic of Tatarstan. The airline said on April 3 that the suspension of flights to and from Kazan would come into effect on April 5 and that it was being done "for security reasons." The announcement came a day after a drone attack targeted Tatarstan's industrial facilities in Yelabuga and Nizhnekamsk, injuring 14 people, including foreigners from eight nations, in what appeared to be the deepest such strike inside Russia by Ukrainian armed forces fighting against Russia's ongoing invasion launched in February 2022. Kyiv has not officially claimed responsibility for the attack.
