Prime Minister Justin Trudeau says Iran must take full responsibility for mistakenly shooting down a Ukrainian jetliner, killing all 176 civilians on board, including 57 Canadians.

B次元官网网址淪hooting down a civilian aircraft is horrific. Iran must take full responsibility,B次元官网网址� he said.

Officials from Global Affairs Canada and investigators from the Transportation Safety Board were waiting to get access to Iran so they can both be part of the investigation and provide consular services to families of Canadian victims. Trudeau said three visas had been issued so far and the first members of the team were expected to be on the ground in Iran within the day.

The planeB次元官网网址檚 downing came hours after Iran launched missile attacks at two military bases hosting U.S. troops in Iraq. Those attacks were retaliation for the U.S. killing of IranB次元官网网址檚 top general, Qassem Soleimani, in an American airstrike in Baghdad on Jan. 3.

A military statement delivered on Iranian state television said the civilian airliner was mistaken for a B次元官网网址渉ostile targetB次元官网网址� when it turned toward a sensitive military site belonging to IranB次元官网网址檚 Revolutionary Guard, an elite unit of the countryB次元官网网址檚 military.

IranB次元官网网址檚 Foreign Minister Mohammad Javad Zarif still pointed some blame towards the Americans, saying on Twitter, B次元官网网址渉uman error at time of crisis caused by U.S. adventurism led to disaster.B次元官网网址�

Trudeau said accidents like the downing of the plane are what happen when tension is high and he said things need to calm down in the region.

B次元官网网址淭he reality is there have been significant tensions in that region for a long time and what we are calling for now is a de-escalation to ensure that there are no more tragic accidents,B次元官网网址� he said.

UkraineB次元官网网址檚 president said Iran must issue an official apology and also called for compensation for the disaster. President Volodymyr Zelenskiy said Ukraine expects a B次元官网网址渇ull and open investigation, bringing the perpetrators to justice.B次元官网网址�
