location: Bieh
notes: On 2 May 2021, security forces (variously described as being from the army, police, and/or a new paramilitary entity, and provisionally coded as SSPDF and SSNPS) loyal to the recently appointed county commissioner of Mayom clashed with armed youth (presumed to be Bul Nuer) at a cattle camp in the Byei area (presumed to be an alternate spelling of Bieh) in Mayom county (Unity state). 9 were killed - at least two of whom died later as a result of their wounds - with the majority of those killed appearing to be from the security forces. 3 were wounded. The county commissioner, who is a relative of the powerful Presidential advisor Tut Gatluak, has accused forces loyal to ex-Maj. Gen. Stephen Buay of being involved in the clash, which he says was sparked by an attempt by security forces to retrieve stolen cattle. The following day, Stephen Buay announced his defection to Paul Malong's South Sudan United Front, citing the attack on the cattle camp as a reason for his return to arms.
