Tanzim, or Organization, is a loosely organized Fatah militia, which spearheaded some of the riots and traded fire with
Israeli troops during September-October 2000. The Tanzim fighters,
although nominally under Marwan Barghouti's control, are often no
more than a ragtag group that does not wait for orders to open fire
when confronted with Israeli troops shooting at rioters. Although Yasir
Arafat has funded the Tanzim fighters and provided their weapons,
plenty of other Palestinians with arms--often purchased from
Israelis--also act as freelance fighters on the street.
