Monday's attack came just hours after a senior international mediator working to resolve the conflict said the region was now "stable".
A peacekeeper from the UN-African Union Mission in Darfur (UNAMID) was also wounded in the attack on the makeshift camp in Sortoni where tens of thousands of people have taken refuge from an upsurge in fighting this year between the army and ethnic minority rebels.
The UN Humanitarian Coordinator in Sudan, Marta Ruedas, "condemns the reported shooting and killing of six civilians, including two children, by armed local tribes in Sortoni", a statement said.
Insisting that the region was secure, he said that "there are some isolated incidents still occurring".
"But this is normal as the region is coming out of a war," Sissi told reporters.
A camp resident told AFP that gunmen on camels and in pick-up trucks attacked twice using rocket-propelled grenades and machineguns.
The UN Office for the Coordination of Humanitarian Affairs said the attack followed a "reported rise in tensions between displaced people and armed tribesmen over cattle raiding".
In a separate statement UNAMID said its peacekeepers had "apprehended two of the alleged perpetrators of the attack" who were now being handed over to the Sudanese authorities.
