Iranian local media have reported at least 44 fatalities after a head on collision between two buses near the city of Qom around 100 kilometers south of the capital Tehran.
The accident which is reported to have taken place Monday evening has been blamed on a burst tire on one of the buses which caused it to swerve out of control and directly into the second oncoming bus.
Head of Traffic Police in Qom province, Col Ardeshir Jamshidi-rad, was quoted by the news agency AFP as saying: "The driver of a bus travelling from Isfahan lost control of his vehicle after one of his tires burst."
Adding: "He hit a car before finding himself in the oncoming lane, where he hit another bus. The two vehicles caught fire immediately."
