DHAKA: Kenya is mourning 148 people killed in Thursday’s al-Shabab attack on Garissa university campus, amid questions over why warnings were ignored.

Kenyan newspapers say there was intelligence information of an imminent attack on a school or university.

Locals question why security was not heightened, with only two guards on duty at the time of the attack, reports the BBC.

Four more people have been found alive on the campus, but two are suspects and have been arrested, sources say.

One is said to be a Tanzanian national with no known links to the university.

All the bodies have been removed from the scene, Kenya’s interior minister Joseph Nkaiserry said. Most of the victims were students, but three police officers and three soldiers were also killed, he added.

Police in neighboring Uganda say they have received information suggesting a similar attack is being planned there.
