ran is refusing to hand over the black box of the doomed Ukrainian airliner to Boeing amid an investigation into what caused the crash that killed all 176 people aboard the flight out of Tehran early Wednesday, according to a report.

Ali Abedzadeh, the head of Tehran’s civil aviation organization, told Mehr news agency in Tehran that Iran has not made a decision on which country or international authority it would send the black box to for its data to be analyzed, Reuters reported.

The Boeing Company is an American aerospace company headquartered out of Chicago. It is the world’s largest manufacturer of commercial jet transports. Boeing also designs, manufactures and sells military aircraft, helicopters, space vehicles, missiles and communication equipment worldwide.

The crash of the Ukraine International Airlines flight came hours after Iran fired as many as 15 ballistic missiles on Iraqi bases housing U.S. soldiers in a major retaliation by the rogue regime after the U.S. airstrike that killed Iranian Quds Force Gen. Qassem Soleimani last week.

No Americans were aboard the flight. Three Britons, three Germans, 63 Canadians, 10 Swedes, 11 Ukrainians, 82 Iranians and four Afghans died in the crash, Ukraine’s Foreign Ministry Vadym Prystaiko said.

The timing of the crash fueled speculation on social media that the earlier missile strike played a role in the crash shortly after takeoff from the Imam Khomeini International Airport, but authorities have pointed to a mechanical issue.

Qassem Biniaz, a spokesman for Iran’s Road and Transportation Ministry, said one of the plane’s engines caught fire, causing the pilot to lose control of the aircraft, sending it crashing to the ground.
