At least 40 Iranians were injured when a Russian-made Tupolev aircraft caught fire as it landed in Iran’s Mashhad airport on Sunday. No fatalities were reported.
According to Iran's state run media, the incident occurred when the rear end of the plane caught fire while landing.
Mashhad is a popular destination for pilgrims among Iran's majority Shiite Muslims.
Russia's Federal Air Transport Agency said it will investigate the reasons behind the fire, and said weather conditions and visibility problems were most likely the cause of the incident.
Iran has suffered a string of crashes in the past few decades, many involving Russian-made aircrafts.
