The Boeing 737 crash is believed to have been caused by a mechanical failure, Reuters and The Associated Press reported.

An investigation team was deployed to the site of the accident in Tehran, the AP report said.

Flight data from the airport showed a Boeing 737 flown by Ukraine International Airlines took off on Wednesday. It stopped transmitting data right afterward, according to website FlightRadar24.

“We are following reports that a Ukrainian 737-800 has crashed shortly after takeoff from Tehran. #PS752 departed Tehran at 02:42UTC. Last ADS-B data received at 02:44UTC,” the flight monitoring website said.

A video posted by Iran’s state-backed ISNA news agency showed a faint glow of light in the distance before an explosion could be seen.

Further details about the incident were not provided.

The airline did not immediately respond to the reports.

The crash came just hours after Iran fired missiles at two bases in Iraq that house United States troops in retaliation for the killing of Iranian Gen. Qassam Soleimani.
