The number of people displaced by weekend clashes between the SPLA and armed men in Mangalla has gone up from 600 to 1,200.
Many of the displaced are sheltering at the Dr John Garang Memorial military college while others are scattered in Mangala town and surrounding areas.
At least four people were reported shot dead when fighting erupted between soldiers and armed men during an occasion to inaugurate the commissioner of Mangala County.
A committee has been formed by the national government to investigate the incident.
The minister of interior has also met with the top authorities of the Terekeka and Jubek areas.
Mangalla County commissioner, Hilario Paul says the IDPs are in need of food and medicines.
Paul says some 500 people have returned to their homes but help is needed for the remaining IDPs.
“These people need food and medicines for malaria, we need humanitarian organisations to help” he said.
Meanwhile, the Terekeka information minister, Modi Lomindi says the weekend clashes were politically motivated.
“You can see that the normal civilians within area are not even fighting, so what happened is that the politicians went and caused this problem,” he said.
Lomindi said an action to lower the Terekeka flag in Mangalla was an instigated by politicians.
Lomindi condemned the incident and called on authorities of both Terekeka and Jubek to resolve their disputes peacefully.
