Al-Shabab fighters in Somalia have struck again - managing to evade security measures to stage an attack in downtown Mogadishu.
Their target, yet again, a hotel popular with government leaders and members of parliament.
Al-Shabab have waged a relentless war against the government since being forced from the capital.
The fighters have also attacked neighbouring countries who have sent peacekeeping troops to Somalia.
Somalis have not seen a stable government since 1991.
So, how big a threat is al-Shabab in Africa? And could a strong Somali government defeat them?
