Sudanese media say fierce clashes between two clans of one tribe this week in the country's southern West Kordofan State, have left dozens dead.

The independent Shorouk TV said on Friday at least 37 people died in the fighting, which took place on Tuesday, between the branches of the Hamar tribe, an ethnic Arab tribe. The official SUNA news agency confirmed the violence but didn't give a death toll.

The two warring clans are Awlad Subaih and Jamaaniyah in the district of Al-Nuhud.

It's unclear what sparked the clashes but Sudan Tribune reported that the two sides fought over theft of sheep.

The governor of West Kordofan, Aboul-Qassem al-Amin Baraka, says Sudanese security forces were deployed and the situation is now under control. An investigation is underway into the incident.
