The crash of an Azerbaijani airliner in Kazakhstan has killed 38 of 67 people on board. Azerbaijan Airlines’ Embraer 190 was en route from Azerbaijani capital Baku to the Russian city of Grozny in the North Caucasus on Wednesday when it was diverted for reasons that aren’t fully clear yet.

Russian President Vladimir Putin on Saturday issued an apology for the Azerbaijan Airlines passenger jet crash in Kazakhstan that occurred earlier this week, but stopped short of claiming responsibility for it.

Sources told Reuters the plane had been hit by Russian fire. "It was as if it was drunk - not the same plane anymore," one passenger recalled.

Thirty-eight of 67 onboard flight from Baku to the Chechen city Grozny believed to have been killed. Russian authorities cite bird strike.

A day after an Azerbaijani airliner’s crashed in Kazakhstan, aviation experts say the plane most likely went down after being hit by Russian air defense systems.

U.S. officials say Russia could be behind a passenger plane crash in Kazakhstan that left at least 38 dead Wednesday, but Russia is denying any involvement.
