On 2 April 2015, gunmen stormed the Garissa University College in Garissa, Kenya, killing 148 people, and injuring at least 79. The militant groups Al-Qaeda and Al-Shabaab, which the gunmen claimed to belong to, took responsibility for the attack. The gunmen took over 700 students hostage, freeing Muslims and killing those who identified as Christians. The siege ended the same day, when all four of the attackers were killed. Five men were later arrested in connection with the attack, and a bounty was placed for the arrest of a suspected organizer.
