Russian President Vladimir Putin has apologized to the leader of Azerbaijan after a passenger plane crashed in Kazakhstan for the “tragic incident” that occurred in Russian airspace, the Kremlin said Saturday.

The Kremlin has said that Putin "apologized for the tragic incident" and expressed his "deep and sincere condolences" the the victims' families.

Three survivors of the downed Azerbaijani plane have described the moments on the flight before the crash. Flight attendant Zulfuqar Asadov said his arm was injured during the incident. On 25 December, 38 people died when an Azerbaijan Airlines flight, which had been due to land in Russia, crash-landed in Kazakhstan.
