An Al-Shabaab suicide bomber detonated a massive truck bomb at the Zobe junction in Somalia's capital, Mogadishu, killing 587 people, injuring 316 others, and leaving more than 500 missing.

Harakat al-Shabaab al-Mujahideen simply known as al-Shabaab is a transnational Wahhabi-Salafi Jihadist militant organization. It is involved in the ongoing Somali Civil War, controlling a non-contiguous network of primarily rural areas in southern Somalia that some consider a quasi-state. Since 2011, the group refers to the territory under its control as the Islamic Emirate of Somalia, although it has not formally declared itself as an emirate. Al-Shabaab has invoked takfir to rationalize its terrorist attacks on Somali civilians and civil servants. It is, in a more limited capacity, active elsewhere in East Africa, and has pledged allegiance to the militant organization al-Qaeda. Al-Shabaab has been designated as a terrorist organization by numerous countries, including the United States, the United Kingdom, Australia, and Canada, as well as several EAC and EU member-states. The militant group remains subject to international sanctions imposed by the United Nations Security Council, the European Union, and other jurisdictions.
