• The first report into the Ukraine International Airlines disaster in Iran said that the aircraft was on fire in the air before it crashed and had turned back towards Tehran Airport, suggesting it was trying to return.
• Iran's aviation authority released its preliminary report on Thursday, just one day after Ukrainian Flight 752 crashed in Iran and killed all 176 people on board.
• The report said the plane encountered a technical problem, but did not specify what kind.
• Other Iranian authorities had blamed a technical problem in the hours after the crash, but later walked back their statements.
• Speculation is mounting that something else may have happened to the plane amid military tension between the US and Iran and as the airline defends its plane, maintenance, and crew.
• The final investigation into the causes of the crash is likely to take many more months.
