A Boeing Co. 737 jet carrying at least 170 people crashed in Iran shortly after takeoff due to technical problems, according to local media reports.

State television reported that the plane crashed at 6:22 a.m. local time. Four helicopters and 22 ambulances had been sent to the crash site, according to reports, but severe fire was hampering rescue efforts.

Emergency personnel are trying to rescue any survivors, Pirhossein Koulivand, head of the Iranian Emergency Organization, said on state-run IRINN.
The 737-800 jet was headed for Ukraine, the semi-official Iranian Students News Agency reported. The website flightradar24 showed Ukraine International Airlines Flight 752 left Tehran’s Imam Khomeini International Airport for Kyiv’s Boryspil International Airport early Wednesday morning local time.
