MOGADISHU - Somali Islamist group al Shabaab was responsible for a car bomb that killed a Somali general on Sunday as he was traveling in a convoy in the capital Mogadishu, a radio station linked to the group reported. A car driven by a suicide attacker drove into the convoy. Andalus radio said that 'a mujahid (fighter) was martyred as his suicide car bomb killed General Goobaanle,' using the general's nickname, a common practice in Somalia. The general's proper name is General Mohamed Roble Jimale. The radio report said details would follow later.
