Azerbaijani leader Ilham Aliyev is demanding answers, saying Vladimir Putin's latest apology "isn't enough" and that Moscow must take responsibility.

Azerbaijani President Ilham Aliyev has demanded a full admission of responsibility from Russia for causing the recent Azerbaijan Airlines plane crash in Kazakhstan and has called for those responsible to be punished.

The Kremlin on Thursday declined to say Russian forces accidentally shot at an Azerbaijani plane that crashed last month, despite Baku repeatedly urging it to accept responsibility for the fatal disaster.

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

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.

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.”
