The Al Shabab group, linked to Al-Qaeda, controls large parts of Somali territory. The country's authorities often blame the jihadist group for these attacks.
Al Shabaab regularly attacks Somalia's capital, Mogadishu, and major cities. President Hassan Sheikh Mohamud has launched an offensive against Al Shabaab. Analysts say it is the most severe threat the Islamist group has faced in years.
