Classes resume at Garissa University nearly one year after Al Shabaab attack

There have been small renovations. The walls have been painted with new colors. The dormitory where the attackers went room to room killing students has since been renamed.

A police station has been set up at the school and security presence has upped from four officers to 30.Classes resume Monday at Garissa University College, nine months after the school experienced one of the bloodiest terrorist attacks Kenyan soil.

Gunmen stormed in at dawn, separated Muslims and shot Christians to death. In some cases, the militants forced students to call relatives to listen in during the killings.

By the time security forces arrived hours later, dead students lay in rows, others shot in the back of the head.

Most survivors were transferred to other universities nationwide for the rest of the school year.

But as the university opened its doors, students are still haunted by the massacre and one wonders if it is not too soon for classes to restart.

"Those rooms they're in --there's so many people's blood there," said Risper Nyang'au, who survived the attack. "How will you study? You will think, 'this is where my fellow students died.'"

In April, Nyang'au was attending early morning prayers when Al Shabaab militants threw a grenade into the room and sprayed the room with bullets. As she lay on the ground, multiple bullet wounds to her leg, the attackers went on to murder 148 people, the worst terrorist attack in Kenya since the 1998 embassy
