A video appears to capture the moment a missile struck a Ukrainian passenger plane near Tehran before it crashed, killing all 173 people on board minutes after it took off.
The footage, obtained by the New York Times, shows a bright light speeding into the sky and exploding.
The plane itself did not explode immediately but was on fire as it attempted to fly back towards the airport, before crashing.
Canadian prime minister Justin Trudeau, whose country lost 63 citizens in the crash, said intelligence reports confirmed that the plane was hit by an Iranian surface-to-air missile. Other reports have said that UK and US officials believe Iran may have accidentally shot down the plane.
The Boeing 737‘s crew did not radio for help before it crashed just moments after taking off from Imam Khomeini International Airport in Tehran.
More video footage following the crash shows smouldering remains of the aircraft scattered outside Tehran.
Among the victims aboard Ukraine International Airlines’ Flight PS752 were four Britons, 82 Iranians, 63 Canadians and 11 Ukrainians. The plane’s destination was Kiev.
