The Guardian ran an article on 4 April 2012 on the most recent suicide bombing in Mogadishu. Al-Shabaab quickly took credit for the bombing. Clar Ni Chonghaile wrote the piece, which you can read here.
I am quoted in the article: "These attacks are disruptive and may set back efforts to develop and rebuild Somalia. They will not, however, build support for al-Shabaab. On the contrary, they alienate most Somalis."
