Burning wreckage, rows of bodybags in Iran crash aftermath

It's not immediately clear what destroyed the plane.

Ukraine International Airlines has said that the 737-800, one of the best in its fleet, was flown by experienced pilots.

It is the first fatal incident to hit the airline.

UIA is in the process of trying to modernize its fleet and has ordered three Boeing 737 MAX aircraft, which it has not yet taken delivery of due to continuing safety concerns over the MAX project.
