A mother and her six children were burned to death in southern Somalia on Tuesday, local officials said, adding that the incident was thought to be a related to clan hostilities.
The victims lived in the village of Jeebey outside the port city of Merca, said Mayor Hassan Omar.
The family was attacked by militiamen while they were sleeping, Omar said.
The attackers have not been identified, but officials say tensions have increased between militias representing two clans vying for land.
"The conflict between these two rival militias in the region has quickly been deteriorating for the past two or three years ... Civilians from both clans are targeted deliberately," Omar said.
"Somalis have been killing each other for years, but targeting women and children and burning civilian homes is a new culture," community leader Mohamed Hussein told dpa from Merca.
