An Iranian passenger plane crashed Wednesday in northwest Iran, killing all 168 people on board, state media reported.

The impact gouged a deep trench in the dirt field, which was shown littered with smoking wreckage in footage shown on state TV. It showed a large chunk of a wing, but much of the wreckage appeared to be in small pieces, and emergency workers and witnesses picked around the shredded metal for bodies.

The Russian-made Caspian Airlines jet was heading from Tehran to the Armenian capital Yerevan near the village of Jannatabad outside the city of Qazvin, around 75 miles northwest of Tehran, state television said. It crashed at about 11:30 am, 16 minutes after taking off from Tehran’s Imam Khomeini International Airport, TV reported.

The Qazvin emergency services director Hossein Bahzadpour told the IRNA news agency that the plane was completely destroyed and shattered to pieces, and the wreckage was in flames. “It his highly likely that all the passengers on the flight were killed,” Bahzadpour said.

Iranian Civil Aviation Organization spokesman Reza Jafarzadeh told state television that 153 passengers and 15 crewmembers were on board. State TV said all were killed.

A Caspian Airlines representative told AP in Yerevan that most of the passengers were Armenians, and that some Georgian citizens were also on board. It was not immediately clear whether there were other nationalities on board. The representative spoke on condition of anonymity because she was not authorized to talk to the press.
