Canadian Prime Minister Justin Trudeau said Thursday that evidence suggests an Iranian missile strike brought down the Ukrainian jetliner that plunged from the sky Wednesday outside Tehran.
"We have intelligence from multiple sources, including our allies and our own intelligence. The evidence indicates the plane was shot down by an Iranian surface-to-air missile," Trudeau said during a news conference in Ottawa, one day after all 176 people aboard — including 63 Canadian passengers — died in the crash.
"This may well have been unintentional," he added.
Trudeau cautioned that the findings remained preliminary, saying the situation demands a full investigation in partnership with Iran.
Iranian authorities, for their part, have denied suggestions that its own missile system accidentally brought down the plane.
Prior to Trudeau's address, a spokesperson for Iranian President Hassan Rouhani said the idea that such a mistake could have happened — suggested by President Trump during a news conference Thursday and reported by multiple U.S. media outlets at that point — is simply "impossible."
"We are at a point that satellite images can read our [license] plate numbers, so if there was a missile hitting a plane, then ... the satellite footage would have been available," Iranian presidential spokesman Ali Rabie told NPR's Mary Louise Kelly on Thursday.
"Apart from that, we have the 'black box' [flight data recordings]. We have asked the government of Ukraine to come, and we can give them the black box and analyze it together. Everything will become clear that it was just an accident."
Rabie's comments came just hours after Trump voiced his suspicions about the crash, saying without providing evidence that "somebody could have made a mistake."
Several reports Thursday — including from Newsweek, The Associated Press and CNN — have also cited unnamed U.S. officials who say it's "highly likely" that an Iranian anti-aircraft missile downed the jetliner by accident. NPR has not independently confirmed these reports.
Rabie rebutted these assertions, noting that "Ukraine and any other country can come and they can open" the black box flight data and cockpit recordings — though he added that they did not give them to U.S. officials because "we don't trust them and how they might read the information there."
"There is no issues regarding this that we are trying to hide," he said.
In a preliminary report issued earlier, Iran's Civil Aviation Organization noted that the flight recorders had been damaged in the crash but nevertheless were recovered and now are under review.
The organization found that Flight 752, a Boeing 737-800, was already on fire before the craft hit the ground, though "no radio messages were received by the pilot regarding unusual circumstances." The report also found that the plane had changed direction midflight, suggesting that it "was on its way back to the airport at the time of the crash."
The group offered no final conclusions on the cause of the crash.
Ukraine's President Volodymyr Zelenskiy, for his part, vowed to get to the bottom of what happened.
"Undoubtedly, the priority for Ukraine is to identify the causes of the plane crash. We will surely find out the truth," he said in a recorded statement Thursday. "For this purpose, a thorough and independent investigation will be conducted in accordance with international law."
Oleksiy Danilov, secretary of Ukraine's National Security and Defense Council, is helping lead a joint commission in Tehran. According to a Facebook post by Danilov, the commission made up of international specialists is considering a wide range of theories at the moment — including a technical problem with the engine, a collision with another flying object, a terrorist act or a missile strike.
The Ukrainian official said the commission includes experts who investigated the 2014 attack on Malaysia Airlines Flight 17, which internationalinvestigators say was launched from rebel-held territory in eastern Ukraine using a Russian missile.

In addition to the 63 Canadians on Flight 752, 82 Iranians and 11 Ukrainians were aboard. Passengers from Sweden, Afghanistan, Germany and the U.K. were all killed in the crash as well.
Zelenskiy declared Thursday a national day of mourning for Ukraine, with flags across the country ordered to fly at half-staff. He also spoke with leaders in Sweden, Afghanistan and the U.K. to offer his condolences for their countries' losses.
"Yesterday was without exaggeration a tragic day in the history of our countries," he told British Prime Minister Boris Johnson, asking the U.K. to join its investigation into the incident, according to a summary of the call.
The plane crash came amid a period of heightened tensions between Iran and the U.S., sparked last week by the U.S. airstrike that killed prominent Iranian military commander Qassem Soleimani in Iraq. U.S. authorities say they carried out the drone strike — which also killed a major Iraqi militia leader — to prevent planned violence against American diplomats, not long after a throng of protesters tried to storm the U.S. Embassy in Baghdad.
This week, Iran retaliated for that killing with ballistic missile strikes on Iraqi bases hosting U.S. military forces, in an operation that came within hours of the of the plane crash outside Tehran.
As for the investigation into the causes of the jetliner's crash, the Canadian prime minister vowed to get to the bottom of what happened.
"In the coming days and weeks, our government will continue to work closely with its partners to ensure that this crash is thoroughly investigated," Trudeau said. "Canadians have questions, and they deserve answers." Copyright 2020 NPR. To see more, visit https://www.npr.org.
