The number of people killed by al-Shabab militants in an attack on a university in northeastern Kenya has risen to 147, government officials say.
The operation to secure the Garissa University College campus was now over, with all four attackers killed, they added.
Some 587 students escaped, 79 of whom were injured.
The gunmen were wearing suicide vests, according to reports, and were armed with AK-47s.
Interior Minister Joseph Nkaissery said the militants exploded "like bombs" as the siege ended, according to the Associated Press. Some officers were wounded by shrapnel.
