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.

"We can clearly say today that the plane was shot down by Russia," President Ilham Aliyev said in a televised statement

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.”
