Ukranian President Volodymyr Zelenskyy delivered an impassioned speech to the Canadian parliament on Tuesday urging them to exert more economic and military pressure on Russia as it continues its invasion of Ukraine.

“Justin, can you imagine you and your children hearing all these severe explosions, the bombing of the airport, the bombing of the Ottawa airport?” Zelenskyy said, speaking to Canada’s Prime Minister Justin Trudeau. “Cruise missiles are falling down and your children are asking you ‘What happened?’”

Zelenskyy implored the Canadian government to establish a no-fly zone over Ukraine to help protect Ukrainian forces from Russian jets.

“Please close the sky, close the airspace,” he said. “Please stop the bombing. How many more cruise missiles have to fall on our cities until you make this happen?”

“Dear Justin, dear guests. Can you imagine that every day you receive memorandums about the number of casualties, including women and children?” Zelenskyy added. “You heard about the bombings. Currently we have 97 children that died during this war.”
