"One day, people invented airplanes. One day, people invented weapons. But will people ever be able to find an effective way to protect themselves from their inventions? And could people ever invent words able to describe our common unbearable pain because of the tragedy of the downed Boeing-737?" he wrote.

According to Zelensky, historically, Ukraine and Canada have a lot in common, and now the two friendly countries are unfortunately united by a common grief.

"My sincere condolences to the families and loved ones of the deceased citizens of Canada and Ukraine. My sincere condolences to the families and loved ones of the deceased citizens of other countries – Iran, Sweden, the United Kingdom, and Afghanistan. Eternal memory to the deceased!" Zelensky wrote in the book of memory.

The president also expressed his condolences to the Canadian people over the tragedy in a conversation with Ambassador Extraordinary and Plenipotentiary of Canada to Ukraine Larisa Galadza.

Zelensky said that 45 Ukrainian specialists had been sent to Iran to participate in the investigation into the causes of the plane crash. Some of them have already returned to Ukraine. At the same time, 10 experts remain in Tehran and continue their work.

Ambassador Galadza thanked Ukraine for its cooperation in the investigation. The parties agreed that the truth would have to be established in that matter.

The president also informed about his meeting with relatives of Ukraine's victims of flight PS752 and said they would be provided support from the Ukrainian government.
