The national airlines of Azerbaijan and Kazakhstan have suspended some flights to Russia after evidence suggested an Azerbaijani plane had been downed by Russian air defence systems. The Kazakh airline,

Azerbaijan's flag carrier announced Friday that it will suspend flights to several Russian airports, citing potential flight safety risks after a crash of one of its planes that many experts blamed on Russian air defense fire.

Experts say evidence in the Azerbaijan Airlines plane crash in Kazakhstan points to a possible midair explosion, not an encounter with a flock of birds.
