Al-Shabaab is considered one of the most dangerous African terrorist organizations. Al-Shabaab is a multi-ethnic militant group based in Somalia that uses numerous terrorist tactics in an attempt to take control of the Somali country. They use many forms of terrorism, including revolutionary, dissident, and nationalist ideological terrorism, as they aim to take power over a territory by overthrowing the government. Al-Shabaab is suspected of involvement in numerous terrorist attacks, including the 1998 US embassy bombings. The motive for their violence is their goal of creating an Islamic state in Somalia, which they believe is morally justified by their ideological beliefs. An important psychological factor behind their violence is the struggle for power over the regions of Somalia and the death of their first leader, "Aryo". They use his death as justification for violence against outside nations who interfere with their goal. Al-Shabaab means “The Youth” and is also considered a jihadist group. Their number is estimated at between four thousand and six thousand militants, making them a major terrorist threat. In 2012, the United States Department of State placed a bounty on Al-Shabaab leaders and insurgents Moktar Ali Zubeyr "Godane", Ibrahim Haji Jama, Fuad Mohamed Khalaf, Bashir Mohamed Mahamoud, and Mukhtar Robow (Department of State State of the United States, 2012). .
