Canada and several other countries whose citizens died as a result of the downing of the Ukraine International Airlines (UIA) plane flight PS752 near Tehran have asked Iran to postpone the decryption of flight recorders to a later date.

As explained by the Canadian Transport Safety Council on Sunday, April 12, the decision was caused by restrictions imposed to combat the spread of COVID-19 and making it difficult for experts to arrive, Deutsche Welle's Russian service reports.

Iran contacted interested parties a few days earlier to find out when experts would arrive to help decrypt data from black boxes. In response to a request, Canada assured the Islamic Republic's authorities that it is looking forward to downloading and deciphering data.

However, this requires the actual presence of experts from several countries so the decryption should be postponed until there are sufficient conditions for a safe trip, the Canadian side said.
