A suicide bomber blew himself up Wednesday at the compound of Somali President Sharif Sheikh Ahmed, killing at least two people, in an attack claimed by Al-Qaeda affiliated Shebab rebels. The bomber detonated an explosive vest at the highly guarded compound, but it was not immediately clear if Sharif, who was in Ethiopia on Tuesday, was back at his residence. The Shebab said one of its volunteers had carried out the attack, claiming 16 people had been killed. “The mujahideen carried out a spectacular martyrdom operation inside the presidential palace of the apostate Somali regime,” the group said in a Twitter post. Police spokesman Abdulahi Hasan Barise said that according to initial reports at least three people had been killed, including the bomber, and that six others had been injured.
