Azerbaijan says the plane had multiple holes in its fuselage and that the occupants had sustained injuries ‘due to foreign particles penetrating the cabin mid-flight’

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.

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