Community leaders on Kenya's coast are warning that Islamic extremism is on the rise.
The killing in August of a Muslim cleric was followed by days of deadly riots in the city of Mombasa, from where the BBC's Gabriel Gatehouse reports on a region caught between economic deprivation and religious fundamentalism.
We met Yusuf Mohamed in an obscure back street of Mombasa.
As the mosques filled up for Friday prayers, we discussed the topic the whole neighbourhood was talking about: The recent drive-by assassination of Sheikh Aboud Rogo Mohammed.
The preacher had been driving north of the city.
A vehicle pulled up alongside his car. A gunman - or gunmen - shot him dead at close range.
Mr Rogo's wife was in the car with him. She was injured, but survived.
"They killed him as an animal, not as a human being," Mr Mohamed said.
Nervous
In his 20s, and like many young men in the mainly Muslim city of Mombasa, Mr Mohamed is unemployed.
Sometimes he prays at the Masjid Musa, the mosque where Mr Rogo used to preach.
He said people in the neighbourhood were nervous.
