Australian Prime Minister Scott Morrison said Friday the downing of a Ukrainian plane in Tehran "does not suggest an intentional act."
His comments come after multiple US officials have said the US increasingly believes that Iran mistakenly shot down a Ukrainian airliner on Wednesday.
"Australia has received similar intelligence to that which has been spoken to by both the Prime Minister of Canada and from the United States," Morrison told reporters in Canberra.
"It is just a terrible, terrible event and we'll provide whatever support we can."
The Australian Prime Minister also called for a probe into the disaster, saying "it is absolutely critical that full and transparent investigation is undertaken into this terrible event and that would include undertaking all efforts to ensure we get recovery of the black box recorder that can obviously inform that investigation."
Australia’s flag carrier, Qantas, said earlier this week it is "adjusting its flight paths over the Middle East to avoid the airspace over Iraq and Iran until further notice."
