Iran pledged Wednesday at a meeting of UN civil aviation agency to hand over black boxes from downed Flight 752 to Ukraine or France for analysis -- a move welcomed by Canada and Ukraine. Irans representative at the International Civil Aviation Organization in Montreal, Farhad Parvaresh, said the devices would be sent to Kiev, sources confirmed to Agence France Presse. They are expected to contain information about the last moments before the Ukraine International Airlines jetliner was on January 8 struck by a missile and crashed shortly after taking off from the Tehran airport, killing 176 people. In Ottawa, Canadian Foreign Minister Francois-Philippe Champagne described Irans commitment to finally share the black boxes as "a step in the right direction by Iran." "I take Iran at their word," he said, "but I would rather judge their actions once the black boxes are in Europe and we have our own experts who have been able to analyze (them)." Ukraines ambassador to Canada, Andriy Schevchenko, in a tweet said his country also "welcomes Irans decision" to hand them over, adding that "if additional expertise is needed," the flight data recorders would be forwarded to France for analysis. Iran has admitted that the two black boxes were damaged and that it lacked the technical ability to extract data from them, but for two months it has waffled about what to do with them. Countries whose citizens died in the disaster -- which included mostly Iranians but also Afghans, Britons, Canadians, Swedes and Ukrainians -- had criticized Irans refusal to hand the planes black boxes to Ukraine or one of the few countries capable of recovering and analyzing the data they contain.  Canada repeatedly asked Iran to hand the planes black boxes over to Ukraine or France for expert analysis.  At the ICAO meeting, Canadian Transportation Minister Marc Garneau stepped up the pressure, saying: "We cannot learn from the tragic shoot-down of PS752 unless all the facts are known and analyzed.  "Two months after the fact, we should all be increasingly concerned with Irans failure to arrange for the readout of the flight recorders despite repeated requests," he said, according to his speaking notes. "Iran must act now to arrange the readout of the flight recorders as a demonstration of continued willingness to provide a full and transparent account of this event that is consistent with their international obligations. Canadians and the international community simply cannot wait any longer." The ICAO also pressed Tehran "to conduct the accident investigation in a timely manner" in compliance with international accident investigation provisions. The disaster unfolded as Irans defenses were on high alert in case the US retaliated to Iranian strikes hours earlier on American troops stationed in Iraq -- which were themselves in response to the US killing of Quds Force commander Qassem Soleimani.
