At least 77 people were killed and 27 injured when an IranAir-operated passenger plane crashed near Lake Orumiyeh, 700 kilometers (almost 435 miles) northwest of Tehran, after it took off from the capital's Mehrabad International Airport on Sunday
The plane reportedly headed for the runway to land but was forced to abort touchdown due to inclement weather conditions. The aircraft then disappeared from radar and crashed in a farmland after making a second attempt to land in the early evening hours.
Following the heartfelt incident in Orumiyeh, Iranian Minister of Roads and Transportation Hamid Behbahani said on Sunday that the government has launched a probe into the cause of the crash.
"The two black boxes of the plane have been found and it will take a while until the fact-finding committee can discover the main cause of the incident," Behbahani noted.
There have been 29 cases of plane crashes in Iran since the victory of the Islamic Revolution in 1979, which have caused the loss of more than 1,600 lives
In Iran's worst air accident, a Russian-made Ilyushin 76 crashed in the mountains of southeastern Iran in February 2003, killing 302 people onboard
