During the 15-hour attack on Garissa University in Kenya by the Somali militant group al-Shabaab, inadequate communication was demonstrated at all levels. On April 2, four al-Shabaab gunmen attacked the university, taking more than 700 students hostage, killing at least 148 people, and wounding another 79. Poor execution of emergency response planning led to this event being the third deadliest terrorist attack in the world since 2010.
