Iran will send to Ukraine the black boxes from the Boeing 737-800 that its military mistakenly shot down shortly after takeoff from an airport in Tehran this month, the official Tasnim News Agency reported on Saturday.

A director in charge of accident investigations at the country’s Civil Aviation Organization, Hassan Rezaifar, said that the cockpit and flight data recorders from the plane, Ukraine International Flight 752, would be transferred to Ukraine at the request of the country’s authorities.

The devices had not been read in Iran, he said, and they would be examined “with the use of the expertise of the countries of France, Canada and America,” according to Tasnim. There were 57 Canadians among the 176 people killed on the plane, alongside 11 Ukrainians and 82 Iranians.

It remained unclear when the black boxes would be transferred to Ukraine, or when experts would start analyzing them. A spokeswoman for President Volodymyr Zelensky of Ukraine said that she could not confirm that the black boxes were, in fact, bound for the country.
