The deadly Christmas Day crash of an Azerbaijani plane in Kazakhstan was likely caused by a Russian air defence system, military and aviation experts have said. It comes after sources close to Azerbaijan’s investigation into the incident said fire from a Russian Pantsir-S air defence system was believed to be behind the devastating crash,

Azerbaijan's transport minister has said the Azerbaijan Airlines plane that crashed on 25 December was subjected to "external interference" and damaged inside and out, as it tried to land in Russia's southern republic of Chechnya.

An investigation into the deadly crash of an Azerbaijan Airlines flight in Kazakhstan earlier this week came after the passenger plane experienced “physical and technical external interference,” the carrier said Friday.
