The son of a Kenyan government official has been identified as one of the gunmen who took part in an Islamic extremist attack on a university that killed 148 people.

Islamic extremists from Somalia killed 36 quarry workers in northern Kenya early today, targeting non-Muslims just like an attack 10 days ago on bus passengers.

A primary school headteacher who was the only survivor of the Kenya bus massacre has said he was saved because his would-be killers became confused as he lay waiting to be murdered.
