A Somali official says a suicide bomber has killed at least three civilians, including a young boy, at a restaurant in Somalia’s capital.

The spokesman for Somalia’s information ministry tells The Associated Press that seven other people were injured when the bomber detonated a suicide vest outside the restaurant near a security checkpoint close to the presidential palace in Mogadishu.

There is no immediate claim of responsibility for the blast, but the al-Qaida-linked al-Shabab extremist group often carries out such attacks.
