The violence follows the killing of at least 83 people on Saturday and Sunday in West Darfur.
Clashes between rival ethnic groups in the Sudanese state of South Darfur have left 47 people dead, a day after more than 80 people were killed in separate clashes elsewhere in the troubled region.
“The clashes between the Rizeigat tribe and the Fallata tribe have ceased and we have now counted 47 dead,” local chief Mohamed Saleh told AFP news agency on Monday.
Saleh, of the ethnically non-Arab Fallata people, added that several houses were set on fire in the attack.
The violence – which erupted early on Monday – came after at least 83 people were murdered in clashes between rival ethnic groups on Saturday and Sunday in West Darfur state.
The clashes came about two weeks after United Nations peacekeepers halted patrols in the Darfur region, preparing for a full withdrawal.
Violence in the two states is one of the most significant fighting reported since the signing of a peace agreement in October, which observers hoped would end years of war.
While the former rebel forces pledged to lay down their arms, decades of conflict have left the vast western region awash in arms and divided by bitter rivalry.
The main issues include land ownership and access to water.
Sudan has undergone a fragile transition since the ousting of President Omar al-Bashir in April 2019 following mass protests against his regime.

Darfur suffered from a bitter conflict that erupted in 2003, leaving an estimated 300,000 dead and 2.5 million displaced, according to the UN.
The main conflict has subsided over the years, but ethnic and tribal clashes still erupt periodically, largely pitting nomadic Arab pastoralists against settled farmers from non-Arab ethnic groups.
Only two groups refrained from signing the peace agreement, one of which enjoys considerable support in Darfur.
The UN-African Union Hybrid Operation in Darfur, a peacekeeping force, plans to phase out some 8,000 armed and civilian personnel within six months.
