Tanzim
Tanzim (Arabic: التنظيم Al-Tanẓīm, "The Organization") was a term used by Palestinians to refer to the grassroots organisation of Fatah in Palestine during the 1990s and early 2000s, and by Israeli and American sources to refer to an alleged armed organisation said to operate within Fatah.
On 4 December 2001, Israel proscribed "Tanzim" as a terrorist organisation. No organisation by that name has been proscribed by any other countries.
