A cargo plane crash near Tehran, the capital of Iran, has left all but one of the people aboard dead, Iranian media reported Monday.
Iran's army, which was deployed to the site following the crash, confirmed that 15 people had been killed in the incident.
The Boeing 707 aircraft, carrying meat products from the Kyrgyz capital, Bishkek, was attempting to land at Fath airport in Karaj, 40km (25 miles) west of Tehran.
The cause of the crash is being investigated, but it is thought that poor weather conditions may have contributed.
The plane came off the runway and hit a residential area, but no people on the ground were killed. Of the 16 people aboard the cargo plane, only a flight engineer was found alive.
An army spokesman confirmed to state TV that the plane belonged to Iran, and that all those on board were Iranian citizens.
This is the latest in a series of plane crashes in Iran in recent years. Aseman Airlines was ordered to ground its fleet of ATR planes in February last year after one of them crashed into the Zagros mountains, killing all 66 aboard.
In August 2014, a Sepahan Airlines' Antonov plane crashed shortly after taking off from Tehran, killing 39 of the 40 people on board. It is believed engine failure was the cause.
The poor aviation record is partly a result of US sanctions that have prevented officials from purchasing new planes and critical spare parts.
A landmark 2015 deal between Tehran and Washington brought renewed hope that the situation would change - but the US pulled out of the deal and reinstated sanctions in May.
