Three masked members of a militant Islamist group in Somalia last week shot and killed a Somali Christian who declined to wear a veil as prescribed by Muslim custom, according to a Christian source in Somalia. Members of the comparatively “moderate” Suna Waljameca group killed Amina Muse Ali, 45, on Oct. 19 at 9:30 p.m. in her home in Galkayo, in Somalia’s autonomous Puntland region, said the source who requested anonymity for security reasons.
