The Ukraine International Airlines crashed at about 6.20am this morning, killing everyone on board. The tragedy came just hours after Tehran launched over a dozen missiles at two US bases in Iraq, prompting some commentators to claim the plan had been shot down by Iranian air defences. But the cause of the crash is yet to be determined and Iran has vowed to shut out American authorities from the investigation.
Hours after the crash, which killed all 167 passengers and nine crew members onboard the aircraft, rescue workers discovered the plane’s two black boxes - which records the jet’s flight data and will play a key role in determining the cause of the crash.
But Iran is refusing to hand the data over to international authorities.
Speaking to Iran’s semi-official Mehr news agency, the head of Iran’s Civil Aviation Authority, Ali Abedzadeh said the black boxes would be analysed in the country where the accident took place, in accordance with International Civil Aviation Organisation (ICAO) rules.
He added that Ukrainian investigators would be part of the process and ruled out involving the US at this stage.

He said: “We will not give the black boxes to the manufacturer [Boeing] or America.”
Ukraine’s Tehran embassy initially blamed engine failure for the cause of the crash, but has since removed the statement and said no official comment could be made until after the investigation had concluded.
Horrifying footage posted online shows the Boeing 737 engulfed in flames as it went down, landing just outside of Tehran.
Images of the jet’s debris appear to show shrapnel holes, which has prompted some experts to claim the plane was shot down.
