A Jamaican-born Muslim cleric has been sent back to Kenya after an attempt to deport him failed.

Kenya says Abdullah el-Faisal is a security threat, and tried to deport him last Thursday.

After Nigeria refused to issue him a transit visa, he was sent back to where he had come from.

El-Faisal has previously served four years in a British prison for inciting murder and racial hatred.
