What we know
It was not immediately clear what caused the Boeing 737-800 aircraft to crash, but Iranian news agency Fars reported it was suspected to have been caused by technical issues, as did Iran's official news agency IRNA.
Iran's civil aviation spokesperson Reza Jafarzadeh said that an investigation team was present at the site of the crash close to the airport in the southwestern peripheries of Tehran, the Associated Press reported.
"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.''
According to air tracking service FlightRadar24, flight data from Imam Khomeini International Airport showed that a Ukrainian 737-800 aircraft flown by Ukraine International Airlines took off Wednesday morning, then stopped sending data almost immediately afterward.
The Boeing plane had left Tehran bound for Boryspil airport, Kyiv, Iran's Isna news agency said, adding that 10 ambulances were sent to the crash site.
A Boeing Co. spokesperson told the Associated Press the company was "aware of the media reports out of Iran and we are gathering more information."
The crash came hours after Iran launched a ballistic missile attack targeting two bases in Iraq hosting US forces in retaliation for the killing of General Qassem Soleimani.
Condolences for the victims
Ukraine's foreign minister Vadym Prystaiko released the nationalities of those killed in the crash in a tweet. Among the passengers, 82 were Iranian, 63 were Canadian, two passengers and the nine crew members were from Ukraine, 10 were Swedish, four were from Afghanistan, three from Germany and three from the UK.
Ukraine's President Volodymyr Zelenskiy has expressed "sincere condolences to the relatives and friends of all passengers and crew" and has cut short a visit to Oman following the incident.
Boeing record in spotlight
The Boeing 737-800 aircraft have been involved in a number of fatal accidents over the years. In March 2016, a Flydubai 737-800 from Dubai crashed while trying to land at Rostov-on-Don airport in Russia. Sixty-two people aboard lost their lives.
Aviation expert Geoffrey Thomas, however, praised the aircraft's "excellent safety record" adding that it was "the most reliable airplane in commercial operation today" with over 7,000 such aircraft in operation around the world.
The crash was Ukraine International Airlines' first fatal crash, which previously had "a perfect safety record" said Thomas, speaking to Deutsche Welle.
The Boeing 737-800 is an older model than the Boeing 737 MAX, which has been grounded for almost 10 months following two crashes, one in Ethiopia and the other in Indonesia.
FlightRadar24 said the Ukrainian flight on Wednesday was not operated by a Boeing 737 MAX.
Iran has suffered a series of fatal air accidents in recent years. Decades of international sanctions imposed on the country has taken a toll on its commercial passenger aircraft fleet.
