Azerbaijan’s leader on Monday accused Moscow of carrying out a “cover up” over a passenger jet crash last month that claimed 38 lives, as relations sour between the two neighbors.

Azerbaijan’s President Ilham Aliyev says the Azerbaijani airliner that crashed last week was shot down by Russia, albeit unintentionally.

In the crash’s aftermath, Azerbaijan has unleashed rare and stinging criticism of Russia, with the country’s president saying Moscow’s response has caused “surprise, regret and rightful indignation.”

We demand justice, we demand punishment for those responsible, we demand full transparency - said the President of Azerbaijan, Ilham Aliyev, regarding the plane crash caused by a Russian missile. He also accused Moscow of attempting to cover up the incident.

Azerbaijan's president has confronted Putin over the devastating plane crash that killed 38 people on Christmas Day.
