All 176 on board were killed when the Ukrainian aircraft crashed shortly after taking off from Tehran International Airport. It was going to Kiev in Ukraine but many on board would then move on to Canada.

According to the passenger list, several Swedes were aboard the affected plane. On Wednesday, the Foreign Ministry confirmed in an e-mail to TT that "a number of Swedes have been killed in the plane crash in Iran", while at the same time saying that they are working to get precise clarity in the figures.

In addition to the Swedes, there were 82 Iranians, 63 Canadians as well as Afghans, Germans and Britons on board. According to the Security Council of Ukraine, eleven Ukrainian citizens were also killed, including the nine crew members.

"We share your sorrow"

Canada states that as many as 138 of the victims would go on to Canada, and many of them were young.

-No words can take away your pain, but I want you to know that a whole country is behind you. We share your sadness, says Prime Minister Justin Trudeau to the victims' relatives.

Several dozen of those killed came from a large Iranian population around the city of Edmonton, including at least two newlyweds and their relatives, as well as a number of college students.

"All the fatalities had so much potential, so much life ahead of them," says Trudeau, who also says that he assumes that Canada will have an active role in the investigation of the accident.

Requested inquiry

Both Canada and the United States have requested a basic investigation into the cause of the accident.

Representatives of the airline Ukraine International Airlines write in a statement that the risk of the crew making a mistake is minimal. There are no immediate signs of an attack and Ukrainian President Volodomyr Zelenskyj warns of speculation.

"Our priority now is to find out the truth and who is responsible for this terrible disaster," Zelenskyj writes in a statement on Facebook.
