Russia’s President Vladimir Putin has apologized for the fact that an Azerbaijan Airlines flight crashed after entering Russian airspace in Grozny, Chechnya on Wednesday, but did not say that Russia was responsible.

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

On 25 December, 38 people died when an Azerbaijan Airlines flight, which had been due to land in Russia, crash-landed in Kazakhstan. The circumstances around the crash remain unclear, but limited evidence so far suggests it may have been hit by missiles fired by a Russian air-defence system as it tried to land in Chechnya.
