At least 77 people were killed and 27 injured when an IranAir-operated passenger plane crashed near the city of Orumiyeh, West Azarbaijan Province, Sunday night, Head of Orumiyeh University of Medical Sciences Nosrat Molazadeh said on Monday.
The official added that all 27 people who were injured in the accident were transferred to hospitals in Orumiyeh.
The plane crashed near Lake Orumiyeh (700 kilometers northwest of the Iranian capital, Tehran), head of Iran's State Emergency Center Gholam-Reza Masoumi said on Sunday.
The American-made Boeing 727 had taken off from Mehrabad International Airport in Tehran, with a one-hour delay and was en route to Orumiyeh International Airport when the incident happened.
The plane reportedly approached the runway to land, but was forced to delay the touchdown due to severe winter weather conditions. The aircraft then disappeared from radar and went down in a farmland after making a second attempt to land.
