Australian Prime Minister Scott Morrison on Friday (10 January 2020) cited intelligence report that showed a Ukrainian commercial was shot down in Tehran.
He reiterated that the incident "does not suggest an intentional act" based on the information.
Morrison said a "full and transparent investigation" is critical for the plane crash.
He reminded Australians that there is "a very restricted advice" on travelling to the region.
A Ukraine International Airlines Boeing 737 burst into flames shortly after take-off from Tehran on Wednesday, killing all 176 people onboard.
The crash happened hours after Iran fired ballistic missiles at U.S. targets in Iraq.
