Khartoum, 26 March-(ANA)-About 750 people have died this month in clashes in South Sudan over cattle-rustling, the United Nations says.
The UN said the fighting was sparked by livestock raids between the Murle and Nuer ethnic groups in Jonglei state.
The delivery of aid to the region has been disrupted, with fighters attacking a food convoy on Tuesday.
The UN says security is deteriorating in South Sudan as ex-rebel fighters stage violent protests over non-payment of benefits for the past five months.
The co-ordinated demonstrations by former fighters in the south's military, the Sudan People's Liberation Army, have paralysed some towns in the Central and Eastern Equatoria regions.
Correspondents say a visit by South Sudan's President Salva Kiir has helped to settle parts of the region but areas in the east are reported to remain tense. (ANA)
