NAIROBI, Kenya (CDN) - A 17-year-old girl in Somalia who converted to Christianity from Islam was shot to death last week in an apparent “honor killing,” area sources said.

Nurta Mohamed Farah, who had fled her village of Bardher, Gedo Region to Galgadud Region to live with relatives after her parents tortured her for leaving Islam, died on Nov. 25. Area sources said they strongly suspected that the two unidentified men in Galgadud Region who shot her in the chest and head with a pistol were relatives or acting on their behest.

“Reports reached the relatives in Galgadud that Nurta Farah had converted to Christianity,” one source said. “The suspicion that the family is responsible is a solid one. The sister was killed in Abudwaq, a district in Galgadud Region, and the place where the incident took place is about 200 meters from where the sister was staying with relatives.”

Relatives buried Farah, sources said. Her parents had severely beaten her for leaving Islam and regularly shackled her to a tree at their home, Christian sources said. She had been confined to her home in Gedo region in southern Somalia since May 10, when her family found out that she had embraced Christianity, said a Christian leader who visited the area.

Her parents also took her to a doctor who prescribed medication for a “mental illness,” he said. Alarmed by her determination to keep her faith, her father, Hassan Kafi Ilmi, and mother, Hawo Godane Haf, decided she had gone crazy and forced her to take the prescribed medication, but it had no effect in swaying her from her faith, the source said.

Traditionally, he added, many Somalis believe the Quran cures the sick, especially the mentally ill, so the Islamic scripture was recited to her twice a week.

She had declined her family’s offer of forgiveness in exchange for renouncing Christianity, the source said. The confinement began after the medication and punishments failed.

Area Christians had reported that Farah was shackled to a tree by day and put in a small, dark room at night.

Somalia’s Transitional Federal Government generally did not enforce protection of religious freedom found in the Transitional Federal Charter, according to the U.S. Department of State’s 2010 International Religious Freedom Report.

“Non-Muslims who practiced their religion openly faced occasional societal harassment,” the report stated. “Conversion from Islam to another religion was considered socially unacceptable. Those suspected of conversion faced harassment or even death from members of their community.”
