Nigerian authorities said Wednesday that a man with ties to al Qaeda plotted last week's car bombing at the United Nations' headquarters in the Nigerian capital that killed 23 people.
The Nigerian State Security Service said Mamman Nur recently returned from Somalia and was "working in concert" with two other suspects who have been arrested. The militant Somali group Al-Shabaab has been linked to al Qaeda.
The secret service described Nur as a "notorious Boko Haram element." Boko Haram, a militant Islamic group, aims to enforce a strict version of Islamic law in Nigeria.
The militant group had claimed responsibility for the attack in which a Honda packed with explosives rammed into the U.N. building, shattering windows and setting the place afire.FULL STORY
