NAIROBI, Kenya, October 27 (Compass Direct News) – Among at least 24 aid workers killed in Somalia this year was one who was beheaded last month specifically for converting from Islam to Christianity, among other charges, according to an eyewitness. Muslim extremists from the al Shabab group fighting the transitional government on Sept. 23 sliced the head off of Mansuur Mohammed, 25, a World Food Program (WFP) worker, before horrified onlookers of Manyafulka village, 10 kilometers (six miles) from Baidoa.

The militants had intercepted Mohammed and a WFP driver, who managed to escape, earlier in the morning. Sources close to Mohammed’s family said he converted from Islam to Christianity in 2005. The eyewitness, who requested anonymity for security reasons, said the militants that afternoon gathered the villagers of Manyafulka, telling them that they would prepare a feast for them.

Five masked men emerged, carrying guns, wielding Somali swords and dragging the handcuffed Mohammed. One recited the Quran as he proclaimed that Mohammed was a “murtid,” an Arabic term for one who converts from Islam to Christianity. Mohammed remained calm with an expressionless face, never uttering a word, said the eyewitness.
