Russian President Vladimir Putin said Saturday that Russia’s air defense systems were active when an Azerbaijan Airlines flight attempted to land in Grozny, Chechnya on Wednesday.

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’

Azerbaijan Airlines plane crash, likely caused by Russian air defense, shines light on a glaring issue the Kremlin has long swept under the rug.
