The US increasingly believes that Iran mistakenly shot down a Ukrainian airliner on Wednesday, according to multiple US officials. The working theory is based on continuing analysis of data from satellites, radar and electronic data collected routinely by US military and intelligence.
The flight crashed following Iranian strikes on US forces in Iraq.
Iran’s Civil Aviation Organization head, Ali Abedzadeh, said it would not hand the flight data recorders to Boeing or the United States after they were found on Wednesday.
