Witnesses in Somalia's capital Mogadishu say fighting between rival militias has claimed the lives of at least 15 people since Saturday.
Residents say the clashes resumed Monday after a one-day lull.
The fighting was sparked by a territorial dispute between gunmen loyal to Mogadishu's Islamic courts and fighters allied with local warlords. Ten people were killed and 40 wounded in Saturday's clashes.
Somalia has been without an effective central government since 1991, when warlords overthrew former President Mohamed Siad Barre.
The country's interim government, set up in 2004, has been hampered by disputes between political leaders. The interim parliament is scheduled to hold its first meeting on Somali soil this Sunday after previous meetings in Kenya.
