Seven students, two women and five men, lost their lives on the spot while two others died in hospitals. The death toll might further rise as some of the injured are in critical condition.
Tehran police experts are probing into the exact reasons behind the incident.
Iran has a high death rate resulting from road traffic accidents in the world.
The high number of deaths in traffic accidents comes despite major steps taken by the Iranian government over the past years for the enhancement of the quality of the country’s roads and improvement of the safety standards in automotive industry.
