At least 13 civilians have been killed and dozens more injured in clashes between Somali government troops and opposition forces in the capital Mogadishu.
Military officials say the fighting began when al-Shabab rebels attacked government soldiers.
The latest round of fighting began on Friday and follows a lull of about two weeks.
