Azerbaijan President Ilham Aliyev said Russia is behind the Christmas Day crash of an Azerbaijan Airlines plane in Kazakhstan, which killed 38 of the 67 people aboard. The motives of the incident remain unclear.

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.

Azerbaijani President Ilham Aliyev on Sunday demanded that Russia admit that it fired at an Azerbaijan Airlines passenger jet before it crashed, accusing Moscow of initially trying to cover up the cause of the fatal disaster.

"Those responsible must be punished, brought to criminal responsibility, and compensation must be paid," President Ilham Aliyev said.
