Flight records for the plane made by Brazil's Embraer that crashed last week in Kazakhstan are headed to the South American country so the data can be extracted, the Brazilian Air Force said in a statement on Monday.

Russian President Vladimir Putin on Saturday issued an apology for the Azerbaijan Airlines passenger jet crash in Kazakhstan that occurred earlier this week, but stopped short of claiming responsibility for it.

The crash of an Azerbaijani airliner in Kazakhstan has killed 38 of 67 people on board. Azerbaijan Airlines’ Embraer 190 was en route from Azerbaijani capital Baku to the Russian city of Grozny in the North Caucasus on Wednesday when it was diverted for reasons that aren’t fully clear yet.
