A PLANE with 176 people on board crashed shortly after takeoff at an airport in the Iranian capital of Tehran - leaving no survivors.
Three British nationals were believed to have been on board the Ukrainian International Airlines (UAI) flight which was bound for Kyiv, Ukraine.
Mechanical issues linked to engine failure have been blamed for the crash - which happened in the early hours of Wednesday morning, though the precise nature of the cause is yet to be officially determined.
The Ukrainian embassy in Iran stress that the incident has nothing to do with terrorism.
The crash comes just hours after Iran fired ballistic missiles as US forces stationed in Iraq in a retaliatory act for the killing of Iranian military general Qasem Soleimani last week.
The vast majority of passengers were not Ukrainian nationals, security authorities in Kiev said.
Ukraine’s Minister for Foreign Affairs tweeted that the deceased include 82 Iranians, 63 Canadians, 11 Ukrainians, ten Swedes, four Afghans, three Germans and three Britons.
An investigation has now been launched into the crash.
Ukrainian International Airlines said its flight from Tehran to Kyiv disappeared from radar just a "few minutes" after take-off.
In a statement on its website, UAI said: "The airline expresses its deepest condolences to the families of the victims of the air crash and will do everything possible to support the relatives of the victims."
It said the aircraft was built in 2016 and had its last scheduled maintenance on Monday.
