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 extremely rare publicised apology from Putin was the closest Moscow had come to accepting some blame for Wednesday's disaster, although the Kremlin statement did not say Russia had shot down the plane.

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.
