Russian dictator Vladimir Putin apologized to Azerbaijani President Ilham Aliyev for the "tragic incident" involving the Azerbaijan Airlines plane. However, the dictator did not acknowledge the downing of the aircraft,

The apology from Russian President Putin came as allegations mounted that the plane had been shot down by Russian air defenses.

Russian President Vladimir Putin apologized to his Azerbaijani counterpart after an incident in Russian airspace that led to the crash of an Azerbaijan Airlines passenger aircraft on Dec. 25, killing dozens.

Russians who reviewed the transcript of the crew's conversations from the Baku-Grozny flight themselves admit that the air crash was caused by their air defense systems (ADS), according to Andriy Kovalenko,

Vladimir Putin admitted Saturday Russian air defence was working when an Azerbaijani Airlines plane tried to land in Grozny before crashing, breaking the Kremlin's silence as speculation mounted Russia may have accidentally shot the plane.

Putin apologized for the “tragic incident” that occurred in Russian airspace, but the Kremlin did not take responsibility for downing the Azerbaijan Airlines flight.

The White House said Friday there were "early indications" that Russian air defenses downed an Azerbaijan Airlines flight in Kazakhstan.

The Russian leader’s phone call stopped short of acknowledging responsibility for the crash of an Azerbaijan Airlines plane.
