Calm has returned to Mogadishu and so have tens of thousands of refugees. They'd fled the two-year long brutal Ethiopian occupation (that's according to Amnesty) and had been living in dire circumstances since. There is no peace yet in Mogadishu but at least there no fighting, for now. The situation is still tense and fighting could brake out any moment but there is also serious talk about peace.
Islamic scholars, from Somalia and outside, are in Mogadishu and have been mediating between the government and the armed opposition. Why Islamic scholars? because both sides are Islamists calling for the implementation of Sharia. Please read Mohamed Adow's excellent explanation of the current situation here.
