Kenya's air force air-bombed two Somalian al-Shabaab camps on Sunday in the first major military response to last week's university massacre.
The Interior Ministry yesterday said the son of a Kenyan government official has been identified as one of the suspects involved in the killing of at least 148 people at Garissa University College.
Kenya's President Uhuru Kenyatta has declared three days of national mourning following the attack on Garissa university which killed 148 people.
Mr Kenyatta, in an address to the nation, said the entire country felt the sorrow of the victims' families.
He called for unity and described the incident as an attack on humanity.
A student who survived the terror attack on a Kenyan college has told of how she played dead to escape the gunmen.
The attack on a college in Garissa, Kenya, comes a day after President Uhuru Kenyatta declared: ''Kenya is safe".
