A small hospital in Mogadishu where more than a dozen are being treated after a suicide bombing in the Somali capital.br br 15 were killed in the bloody blast at a local restaurant.br br The attack came a week after a suicide bomb outside a hotel where President Hassan Sheikh Mohamud was holding a news conference, just two days into the job.br br The election of President Mohamud last week was hailed by his supporters as a vote for change in a country mired in conflict for more than two decades.br br These attacks underscore the security challenges faced by the political newcomer as African forces battle to quash a five-year insurgency waged by al Shabaab.br br The militia group has shown it can still regroup and easily infiltrate government-controlled areas, and that there remain disenchanted, radicalised Somalis ready to strap on explosive belts.
