Canadian Prime Minister Justin Trudeau on Friday urged Iran to hand over black boxes from last week’s downed airliner to France, saying it has one of the few laboratories capable of properly examining them.

“Iran does not have the level of technical expertise and mostly the equipment necessary to be able to analyze these damaged black boxes quickly,” Trudeau said.

So, he told a press conference, “the right place to send those black boxes to get proper information from them and in a rapid way” is France, adding “that is what we’re encouraging the Iranian authorities to agree to.”

Prystaiko said Tehran would grant a team of investigators from Iran and Canada as the countries that lost the most nationals access to the recorders.

Trudeau said Friday another 29 were permanent residents and that Canada was the final destination for 138 of the 176 passengers and crew on the Kiev-bound plane, including visitors and students.

After initial denials, Iran admitted it shot down the plane “unintentionally” while on high alert after firing missiles at US troops stationed in Iraq in retaliation for the killing of top Iranian commander Qasem Soleimani in a US drone strike.

In Ottawa, Trudeau also pledged interim funds for families of the Canadian victims of the crash, but said he ultimately expects Iran to pony up full compensation.

But, he added, “I have met them and they can’t wait weeks. They need support now.”No Canadian remains so far recovered from the crash have been repatriated. Trudeau said he expects the first to arrive in Canada “in the coming days.”
