Russia’s failure to let the plane land and its refusal to take responsibility for the crash are upsetting a key partner.

Following Azerbaijan's president calling for Moscow to accept blame for downing an Azerbaijani plane, there is growing public anger toward Russia for its apparent attempts to sidestep responsibility for the incident.

Azerbaijan’s President Ilham Aliyev says the Azerbaijani airliner that crashed last week was shot down by Russia, albeit unintentionally.

A passenger plane crashed in Kazakhstan yesterday morning. It was probably shot down by Russia, Reuters reports. According to the agency's sources, Russian air defense shot down the Azerbaijan Airlines plane.

The Azerbaijan Airlines plane flew hundreds of miles off its scheduled route from Baku to Grozny, and crashed on the eastern shore of the Caspian Sea. Russia's aviation watchdog said a bird strike might have been the cause.

Azerbaijan’s President Ilham Aliyev has accused Russia of accidentally shooting down an airliner on Christmas Day in a disaster that killed 38 people, and covering up the cause.

The probe into the Azerbaijan Airlines crash in Kazakhstan is examining the conduct of air traffic controllers after the aircraft encountered difficulty, a source said.
