Kenyan President Uhuru Kenyatta has vowed to respond “in the severest ways possible” to the al-Shabab militant attack on Garissa university in which 148 people died.
In an address to the nation, Mr Kenyatta said the Islamist group posed an “existential threat” to Kenya.
He also said the government would take steps to crack down on those who planned and financed terrorist attacks.
Mr Kenyatta also declared three days of mourning for the victims.
Almost all the dead were students. Another people 79 were injured.
Four militant gunmen were killed, and officials say they are holding five people for questioning – one of whom is believed to be a university security guard.
Buses are transporting more than 600 students and about 50 staff who survived the attacks to their home areas, Garissa governor Nathif Jama Adam told Reuters news agency.
