Black September (group)

The Black September Organization (BSO) (, Munaẓẓamat Aylūl al-aswad) was a Palestinian terrorist organization founded in 1970. It was responsible for the fatal kidnapping and murder of eleven Israeli athletes and officials, and the fatal shooting of a West German policeman, during the 1972 Summer Olympics in Munich, their most publicized event. These events led to the creation of permanent, professional, and military-trained counter-terrorism forces of major European countries, like GSG9 and GIGN, and the reorganization and specialization of already standing units like the Special Air Service of the UK.
