Islamic extremists from the rebel al Shabaab militia in Somalia beheaded a Christian on the outskirts of Mogadishu last month, sources said. The militants fighting the transitional government in Mogadishu murdered Zakaria Hussein Omar, 26, on Jan. 2 in Cee-carfiid village, about 15 kilometers (nine miles) outside of the Somali capital, they said. Omar had worked for a Christian humanitarian organization that al Shabaab banned last year.
