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.

Brazilian investigators have reportedly begun analyzing black boxes of the Azerbaijan Airlines Embraer E190 involved in the crash. The news comes almost two weeks after the regional aircraft operating flight J28243 from Baku to Grozny crash-landed near the city of Aktau in Kazakhstan, killing 38 people.

A minister says all the survivors "heard blast sounds" over Grozny before the plane was diverted to Kazakhstan.

A passenger jet operated by Azerbaijan Airlines crashed near the city of Aktau in Kazakhstan on Wednesday, after diverting from an area of southern Russia where Moscow has repeatedly used air defence systems against Ukrainian attack drones.

Multiple shrapnel holes in the plane’s fuselage and its altitude at the time of incident contradict the bird theory. Azerbaijan accused Russia of hitting the passenger jet with a missile. The pilot did not decide to fly to Aktau;
