The EUPF remains active, however, and its armed wing has reportedly been involved in the South Sudanese Civil War, although to what extent is disputed.
[1] The Ethiopian Unity Patriots Front was founded by ethnic Nuer ex-officials of Mengistu Haile Mariam's Derg regime.
[6][11] From this point onward, it repeatedly managed to seize villages along the Ethiopian-Sudanese border amid heavy clashes with the Ethiopian military.
[11] The EUPF joined the Eritrean-backed Ethiopian People's Patriotic Front rebel alliance in 2000,[5] and was able to capture and hold Akobo in western Gambela in the same year.
[4] The Ethiopian military launched an offensive to retake Akobo from the EUPF in August 2004, but this operation initially failed to make progress due to the difficult terrain.
[13] The Eritrean Air Force supported the rebels in Akobo by transporting newly trained insurgent troops from Eritrea into Gambela Region.
[16] This deal was later criticised by elements of the EUPF who claimed that Pal had decided to agree before sufficiently consulting the rest of the rebel leadership.
[17] Numerous SPLM splinter groups and rebel factions continued to be active in the country, however, fighting the new South Sudanese government under President Salva Kiir Mayardit.
[2] According to the SPLM/A-IO, Ethiopian rebel troops under Thowath Pal Chay aided a South Sudanese government offensive in the Upper Nile region in early 2015.
Ojulu responded by accusing Thowath Pal Chay of being behind these illegal deals, and of arming Anuak youths to prepare a new insurgency against the Ethiopian government.
[2][23] [24] In late 2017, Pal accused the SPLM/A-IO of recruiting Ethiopians into their ranks and Riak of increasing regional tensions, while "fighting for destruction of South Sudan".
Most importantly, Eritrea provided some Oromo, Amhara and Tigrean recruits to the EUPF in 2004, and the rebel group also had a few militant Anuak among its ranks at the time.
