“The plane was a cargo Boeing 707 that overshot the runway during its landing,” Iran’s aviation organisation spokesman Reza Jafarzadeh told state broadcaster IRIB.
Iranian state television showed pictures of a plume of smoke rising from the crash site. Some reports on Iranian media said 10 people were on board and that they were killed.
The TV said rescue teams had been sent to the area, between the airports of Fath and Payam.
“We do not know yet whether it was an Iranian or foreign cargo plane,” a local official told TV.
