At least 50 people were rescued from the crash, the semi-official Fars news agency quoted an official as saying.
Fars said there were 105 people on board, but state TV put the number at 156.
Iran has suffered a string of crashes in the past few decades. U.S. sanctions against Iran have prevented it from buying new aircraft or spare parts from the West.
The last major air crash in Iran was in July 2009 when a Caspian Airlines Tupolev aircraft bound for Armenia caught fire in mid-air and crashed into farmland near the city of Qazvin, killing all 168 people on board.
One of the country`s worst air accidents happened in February 2003 when an Iranian Ilyushin-76 troop carrier crashed in southeast Iran, killing all 276 Revolutionary Guard soldiers and crew aboard. (*)
