Clashes between militias in the Somali capital, Mogadishu, have left 13 people dead, days after some of the heaviest fighting seen in the city for years. The latest violence has been centred in the Daynile and Galgalato districts. Some 200 people have died in clashes this year between militias loyal to Mogadishu's Islamic courts and an alliance of warlords. The fighting is the worst the city has seen for more than a decade.
