In Nigeria, a suicide bomber rammed an explosives-laden car into the building of the UN Headquarters in the capital Abuja on Friday, killing at least 18 people, including two women and a foreigner. The blast, for which a radical Islamist sect Boko Haram has claimed responsibility, destroyed a huge portion of the five-storey building that houses 400 UN employees. Police said, 18 people died in the blast while eight others were injured. Among the dead was an unidentified foreign national besides two women.
