The extraction of flight data from the Brazilian-made Azerbaijan Airlines plane that crashed in Kazakhstan last month was completed at a lab run by Brazil's air force, according to a statement released by the entity on Monday.

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.”

"The blame for this disaster lies with representatives of the Russian Federation," Ilham Aliyev said on Jan. 6.

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.
