The Mujahedin-e Khalq terrorist group (MEK) took responsibility for assassinating Basij commander of the customs area of Tehran in 1363.
According to Habilian, the terrorist group of MEK has confessed to this crime, calling it a daring operation, in No.220 of the Mojahed Magazine- the main press organ of the MEK in the early years of the 1980s.
Based on this document, operatives of the MEK terrorist group carried out a reconnaissance operation, identified Ghasem Bargir who was head of the Basij force in Gomrok region in Tehran, and shot and martyred him on September 12, 1984.
Among the reasons listed by the Mojahed Magazine for his assassination was his position in Basij Force and the role he played in dispatching young people to front line of the Iran-Iraq war.
In the early years of the 1360s, the MEK terrorist group martyred thousands of Iranian citizens because of their interest in revolutionary rituals, support for the Islamic Republic, or membership in revolutionary institutions.
