Officials say military forces were deployed to resolve the conflict between Fallata and Taisha tribes.
At least 36 people have been killed and dozens wounded after clashes between Arab and non-Arab tribes in South Darfur over the weekend.
The fighting broke out on Saturday between the Arab Taisha and ethnic African Fallata tribes in the remote Um Dafuq area of South Darfur, witnesses said.
Official news agency SUNA said calm was restored by Monday.
“Military forces were deployed to the areas of clashes to resolve the conflict between Fallata and Taisha tribes which left 36 killed and 32 wounded,” SUNA reported late on Sunday quoting South Darfur officials.
It was not immediately clear what triggered the clashes but similar fighting often erupts in the Darfur region over land and access to water.
Um Dafuq resident Eissa Omar told AFP news agency “we heard the sound of heavy weapons throughout the fighting” which broke out Saturday and continued on Sunday.
The vast Darfur region, located in western Sudan, has been the scene of similar bouts of violence in recent months.
In April, at least 132 people were killed in West Darfur fighting between members of the Massalit tribe and Arab communities, forcing authorities to impose a state of emergency.
In January, renewed clashes between Arab and non-Arab tribes in the West and South Darfur regions killed more than 250 people.
The violence came as Sudan navigates a rocky transition following the toppling of longtime president Omar al-Bashir in April 2019, after mass protests against his rule.
The transitional government installed after Bashir’s removal has been pushing to end long-running conflicts including in Darfur.
It signed a landmark peace agreement with multiple key rebel groups in October, and it is currently in talks to forge peace with the remaining two holdout groups.
The recent violence in Darfur appeared not to involve any signatories to the October peace deal.
On December 31, a hybrid United Nations and African Union peacekeeping mission ended its operations in Darfur.
Darfur was the site of a bitter 2003 conflict pitting African ethnic minority rebels against Arab nomads backed by the Khartoum government under Bashir.
The deadly conflict – which killed some 300,000 people and displaced 2.5 million – subsided over the years but inter-ethnic clashes still occasionally erupt.
