What do we know about the latest al-Shabab attack in Somalia?

In what appears to be its most significant attack on an African Union base in Somalia in years, Al-Shabab claims to have killed 173 Burundian soldier in a camp 160km north of Mogadishu. But there’s confusion over how many people died. A high ranking Burundian officer has been cited in the press as saying 30 lost their lives, while an official statement from the government said just ten were killed. What is clear is that it will trouble the AU at a time when Somalis were meant to be concentrating on preparing for elections.
