Islamic extremists from Somalia’s rebel Al-Shabaab militants on Friday (Nov. 16) killed a Christian in Somalia’s coastal city of Barawa, accusing him of being a spy and leaving Islam, Christian and Muslim witnesses said.

The extremists beheaded 25-year-old Farhan Haji Mose after monitoring his movements for six months, Christian sources said. Mose drew suspicion when he returned to Barawa, in Somalia’s Lower Shebelle Region, in December 2011 after spending time in Kenya, underground Christians in Somalia told Morning Star News.

Kenya’s population is nearly 83 percent Christian, according to Operation World, while Somalia’s is close to 100 percent Muslim.

A crowd assembled in the coastal city on Friday morning to watch the slaughter of Mose, the sources said.
