NAIROBI, Kenya (AP) — Gunmen shot and killed a moderate Muslim leader on Tuesday, an official said, the fourth prominent Muslim to be shot dead in the coastal city of Mombasa in two years.

Sheik Mohamed Idris, the chairman of the Council of Imams and Preachers of Kenya, was shot as he left a mosque early in the morning. A Mombasa police commander, Henry Ondiek, said neither the motive nor the identities of the killers are known.
