Heavy fighting has broken out between forces of Somalia's transitional government and gunmen loyal to an Ethiopian-backed warlord.
The gun battles began around dawn in the same north Mogadishu area where clashes between government troops and the forces of warlord Mr Musa Sude Yalahow killed at least eight people last week.
Gunfire could be heard a few hours after the fighting broke out, and an official at Mogadishu's Medina hospital said at least 10 people had been brought in with wounds.
Last Friday, hundreds of gunmen loyal to Yalahow and led by militia leader Mr Mohamed Dhereh attacked interior minister Mr Dahir Dayah's house, leaving it in ruins. Mr Dayah was not harmed, but at least eight people were killed and 20 others wounded in the fighting.
Somalia has had no effective central government since opposition leaders ousted dictator Mr Mohamed Siad Barre in 1991.
