Heavy fighting between Islamist militia groups in the town of Gureil, 230 miles north of the Somali capital, killed 12 and wounded more than 20.
Clashes erupted in Somalia over the weekend, leaving 28 dead in incidents.
The two sides shot at each other Saturday, bringing businesses to a standstill and forcing residents to take shelter.
Earlier Friday, mortar shelling by Ethiopian forces in Mogadishu killed at least 16 residents.
The fighting is so heavy, and a barrage of mortar bombs is hitting many parts in our town, killing people and causing heavy damages of buildings.
