Eighty-two Iranians, 63 Canadians, and 11 Ukrainians died onboard flight PS752, according to a tweet from Ukrainian foreign minister Vadym Prystaiko. There were also 10 Swedes, four Afghans, three Germans and three British nationals among the victims, he said.

The Boeing 737 jet operated by Ukraine International Airlines took off early Wednesday en route to the Ukrainian capital Kiev, carrying 167 passengers and nine crew before crashing between the cities of Parand and Shahriar. Witnesses described seeing a fireball in the sky and images of the wreckage show charred parts of the plane strewn over a field.

Canadian Prime Minister Justin Trudeau said 138 of the passengers were supposed to catch a connecting flight to Canada. That flight landed in Toronto Wednesday afternoon with many seats empty.

The captain of the crashed plane has been identified as Volodymyr Gaponenko, an experienced pilot with 11,600 hours flying on Boeing 737 aircraft under his belt. The instructor pilot was Oleksiy Naumkin, also experienced with 12,000 hours on the aircraft. Ukraine International Airlines president, Yevhenii Dykhne, said, «It is impossible that there were mistakes by the crew.»

At a press conference in Kiev, he said Tehran airport was «not a simple airport» and the pilots required several years of training to use it.
