Azerbaijan enacted a national day of mourning on Thursday following a plane crash that killed 38 passengers and left 29 survivors.

The Azerbaijan Airlines Embraer 190 flight left Baku, Azerbaijan, on Wednesday and was slated to land in Grozny, Russia. Instead, the plane crashed in Aktau, Kazakhstan. While investigators are still examining the cause of the crash, this comes amid violence at the Armenia-Azerbaijan and Ukraine-Russia borders.
