Yambio City of Western Equatoria State has been deserted following fierce fighting between SPLA and frustrated local militia, says an area Member of Parliament.
Festo Kumba tells the national parliament on Wednesday that scores of SPLA were killed in the incident.
The population has been displaced to neighbouring Democratic Republic of Congo, the MP says.
Another fighting in Eastern Equatoria State, Ikwoto County between SPLA and residents left scores dead, says an area MP.
Grace Alex Abalang says it is regrettable that SPLA is turning against the civil population.
Government and SPLM/A-In-Opposition in August this year agreed to implement peace amidst external pressure.
But, insecurity remains alarming throughout the country.
In the meantime, Juba is expecting to receive over 200 SPLM/A-IO advance team members on December 11.
