Ukraine said Wednesday it asked Iran to give it the black box flight recorders from the Ukrainian International Airlines plane the Iranian military accidentally shot down last week.

Axar.az reports citing VOA that a statement from Ukraine's prosecutor's office said it is taking all necessary measures to ensure the recorders are properly decrypted and to preserve all evidence as investigators carry out their probe of the incident.

Alexander Ruvin, director of the Kyiv Scientific Research Institute of Forensic Science, told Ukrainian media after returning from leading an investigation team in Iran that Iranian specialists were due to arrive in Kyiv on Wednesday and that analysts expect to begin examining the flight recorders on Monday.
