At least 10 people were reportedly killed on Sunday in fighting between rival clans in Central Somalia.
The clashes that broke out in the town of Beledwayne early on Sunday left more than 20 others injured, among them women and children.
Several houses and business premises were damaged by the heavy shelling and bullets from the warring militias, residents say.
The Somali population is divided into clans and sub-clans that often engage in territorial disputes and political arguments.
Somali government troops and African Union (AU) peacekeepers are in the area, trying to stop the clashes.
