The militant Islamist group Al Shabaab has claimed responsibility, just two months after they retreated from the capitol of Mogadishu, pledging to wage guerilla war against the weak and tenuous interim government. Said a BBC journalist on-site: “…I genuinely feel, it is the worst incident I have seen here in Mogadishu.” source
