Kenyan police have charged five men in court for allegedly participating in an attack by militant group al-Shabab on a university in eastern Kenya in which 148 people were killed.

The five men pleaded not guilty Thursday to 152 counts of committing acts of terrorism in a Magistrates Court.

Four al-Shabab gunmen stormed the Garissa University College at dawn April 2. The attack went on for hours before it was finally ended by a specialized police unit.

Prosecutor Daniel Karuri urged the court to deny the suspects bail. Magistrate Daniel Ochenja directed that they be detained until June 11, when the court will determine whether they will be granted bail.
