Five people have been arrested in connection with an attack on a Kenyan university that killed at least 148 people, CNN reported on Friday, citing Kenyan Interior Minister Joseph Nkaissery.

Masked Al Shabaab gunmen strapped with explosives stormed the Garissa University College campus, some 200 km (120 miles) from the Somali border, in a pre-dawn rampage on Thursday.

CNN gave no further details on the arrests.
