Ukrainian Boeing 737 with 180 people on board crashed near Tehran airport early on Wednesday.
The plane had took off from Imam Khomeini International Airport and was en route Ukraine capital Kyiv. The flight reportedly suffered a technical glitch after takeoff, due to which it crashed. The airliner went down near Tehran Imam Khomeini International Airport, according to local media.
Any reports of casualties were yet not available.
An investigation team was at the site of the crash in southwestern outskirts of Tehran, civil aviation spokesman Reza Jafarzadeh said.
Flight data from the airport showed a Ukrainian 737-800 flown by Ukraine International Airlines took off Wednesday morning, then stopped sending data almost immediately afterward, according to website FlightRadar24.
The airline did not immediately respond to a request for comment.
The crash came hours after Iran launched a ballistic missile attack targeting two bases in Iraq housing US forces in retaliation for the killing of Revolutionary Guard Gen. Qasem Soleimani.
