Iranian official: All on board Ukrainian plane killed

A Ukrainian airplane carrying at least 170 people crashed on Wednesday shortly after takeoff from Tehran's main airport, killing all onboard, state TV reported. The plane had taken off from Imam Khomeini International Airport in the Iranian capital. The crash is suspected to have been caused by mechanical issues, the TV reported, without elaborating. An investigation team was at the site of the crash in southwestern outskirts of Tehran, civil aviation spokesman Reza Jafarzadeh said. “After taking off from Imam Khomeini International Airport, it crashed between Parand and Shahriar," Jafarzadeh said. “An investigation team from the national aviation department was dispatched to the location after the news was announced.” Pir Hossein Kulivand, an Iranian emergency official, later told state TV all those on board were killed in the crash. He said rescuers were trying to collect the dead. State TV earlier said there were 180 passengers and crew aboard. The discrepancy could not be immediately reconciled. 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. A photo later published by Iran's state-run IRNA news agency showed rescue officials in a farm field, with what appeared to be pieces of the aircraft laying nearby.<br/>
