The United Nation's refugee agency says 230 civilians have been killed during fighting between government forces and Islamist rebels over the past two weeks in Somalia's capital, Mogadishu.A spokeswoman for the UN High Commissioner for Refugees Melissa Fleming, said the agency is alarmed by the further deterioration in the situation. Ms Fleming said those who have sought refuge in the north of Somalia or in neighbouring countries report the streets of the capital are deserted and people are fearful of leaving their homes. Fighting over the past two weeks between the transitional government and Al Shabaab has cost more than 230 civilian lives with at least 400 people wounded and 23,000 displaced. Unrest in the capital has forced 200,000 people to flee their homes this year alone.
