Dimma (woreda)
Dimma is a woreda in Gambela Region, Ethiopia. Part of the Anuak Zone, Dimma is bordered on the southeast by the Southern Nations, Nationalities and Peoples Region (SNNPR), on the southwest by the Akobo River which separates it from South Sudan, on the north by Gog, and on the northeast by the Mezhenger Zone. The major town in Dimma is Dimma. Originally part of Gog woreda, at some point between the 1994 national census and the 2001 Sample Agricultural Enumeration, Dimma was split from Gog. At first Dimma, along with Gog and Jor woredas, were part of the Administrative Zone 2; however between 2001 and 2007 the Zone was reorganized and Gog became part of the Anuak Zone. The western part of Sheko from SNNPR was also added to Dimma. On 30 January 2004, a group of Anuak rebels attacked a group of outsiders working the gold fields in Dimma. Reportedly 196 people were killed and 25 wounded, most of whom were traditional miners mainly from the SNNPR. This was considered the largest number of civilian casualties in single incident since the December 2003 killings in Gambela. Demographics
