Islamic extremists from Somalia's rebel al Shabaab militants killed a Christian in Somalia's coastal city of Barawa on Nov. 16, accusing him of being a spy and leaving Islam, Morning Star News reports. The extremists beheaded 25-year-old Farhan Haji Mose after monitoring his movements for six months, underground Christians in Somalia said. Mose drew suspicion when he returned to Barawa in December 2011 after spending time in Kenya, which is nearly 83 percent Christian, opposed to Somalia, which is close to 100 percent Muslim. Mose had converted to Christianity in 2010 while in Kenya. Sources said a crowd assembled in Barawa to watch the slaughter of Mose. "His body was split into two, then carried away, only to be dumped near the beach of Barawa city," a Christian who witnessed the murder said. Other Muslim witnesses independently described the same scene, saying the extremists accused Mose of being a spy for foreigners and of embracing the "foreign religion of Christianity." Al Shabaab rebels have killed dozens of Christian converts from Islam since embarking on a campaign to rid Somalia of Christianity. The extremists, variously estimated at 3,000 to 7,000, seek to impose a stricter version of sharia (Islamic law) on Somalia.
