The Black September Organization (BSO) was a Palestinian militant organization founded in 1970. Besides other actions, the group was responsible for the assassination of the Jordanian Prime Minister Wasfi Tal, and the Munich massacre, in which eleven Israeli athletes and officials were kidnapped and killed, as well as a West German policeman dying, during the 1972 Summer Olympics in Munich, their most publicized event. These attacks led to the creation or specialization of permanent counter-terrorism forces in many European countries.

Wasfi Tal was a Jordanian politician, statesman and general. He served as the 15th Prime Minister of Jordan for three separate terms, 1962–63, 1965–67 and 1970 until his assassination in 1971.
