A Ugandan field commander of 341 Battalion serving with the African Union Mission in Somalia (AMISOM) communicates on his radio 30 April 2012, on the frontline near the main road on the northern edge of Maslah Town, the northern city limit of the Somali capital Mogadishu, while a heavy-duty earth-mover fills defensive barriers with sand. AMISOM troops, now numbering 11,400 out of a mandated total of 17,731, supporting forces of the Transitional Federal Government have driven the Al-Qaeda-linked extremist group Al Shabaab out of the Somali capital where life is returning to the seaside city after years of conflict and Somalis are enjoying the longest period of relative peace not experienced since 1991.
