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.
Somali Islamist militants have threatened to stage more attacks in Kenya, after 148 people were killed during an assault at a university on Thursday.
In a statement, the group vowed a long war, saying Kenya's cities will "run red with blood".
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".
