Human rights activists accuse the Kenyan government of killing Muslim leaders because they lack the evidence needed for a conviction in court. In the last two years four Muslim leaders were murdered with no arrests made in the killings. However, the latest killing was of a moderate Muslim who spoke out against the radicalization of Muslims. The previous three murdered Muslim leaders all promoted a radical version of Islam. Last year Sheik Mohamed Idris was attacked by radicalized Muslim youth, leading some to state that his murder was due to radicalized Muslims rather than the government.
