It is too soon to be drawing conclusions of assigning responsibility, Canadian Prime Minister Justin Trudeau said while answering the question of whether the US is responsible for crashed  Ukrainian plane

“How much responsibility does United States bear for this tragedy?” a reporter asked Trudeau. Note that, after killing Iranian military commander Qasem Soleimani by US drone attack, Iran responded firing missiles at US bases, during that night Ukrainian airplane crashed on the ground near capital Tehran.

“The evidence suggests that this is the likely cause, but we need to have a full and complete and credible investigation to establish exactly what happened,” Trudeau responded.

The reporter asked what does he believe that the US is partly responsible for this tragedy?

"I think it is too soon to be drawing conclusions of assigning responsibility, whatever proportions. Right now, our focus is on supporting the families who are grieving across the country and provide what answers we can in a preliminary way, and recognizing that there is going to need to be a full and credible investigation into what exactly happened before we draw conclusions," Canadian PM answered.
