Iran's army said a cargo plane that crashed in Iran's Alborz province on Monday (January 14) was a military plane and that 15 out of the 16 people on board had been killed, the semi-official Fars news agency reported.
"A Boeing cargo 707 place carrying meat from Bishkek in Kyrgyzstan had an emergency landing at Fath airport today ... the flight engineer has been dispatched to the hospital," the army said in a statement carried by Fars.
Earlier Iranian state media said 10 people were on board the plane.
The aircraft went down near Fath airport, near the city of Karaj in the central Iranian province of Alborz.
Fars said the plane crash-landed after "mistaking the airport with another airfield because of the bad weather".
