SourceAbout 150 people are feared dead in a plane crash in north-western Iran.
Iran state television says a Caspian Airlines Tupolev jet was heading from Tehran to the Armenian capital Yerevan when it crashed shortly before midday local time, about 120 kilometres north-west of the capital.
Emergency service authorities have reported the plane was destroyed and shattered into pieces and the wreckage was in flames.
"The passenger plane was completed destroyed and the wreckage was scattered everywhere," IRNA quoted Qazvin police chief Masoud Jafari Nasab as saying.
"Most probably all passengers on board have been killed in the crash," he said, adding that the plane had crashed in farmland near the village of Janat Abad.
Caspian Airlines is jointly owned by Russian and Iranian interests and uses Russian made aircraft.
Iran has had a number of aviation disasters over the past decade, many of which it blames on United States sanctions preventing it from getting spare parts into the country.
