Islamist extremist group, Boko Haram has claimed responsibility for the UN bombing in Abuja. A caller told the BBC on phone that it carried out the attack. Also, another Boko Haram ‘spokesman’ claiming responsibility for the deadly attack said, they were guided by the wisdom of Allah. “Through the wisdom of Allah, we have launched the attack with absolute precision,” the man who identified himself as Abu Darda said in a telephone call to an AFP journalist. “The attack was carefully scripted and executed. We have said it several times that the UN is one of our prime targets.” The veracity of his claim could not be verified.”We will provide details of the martyr who carried out the suicide attack,” the man said. “More attacks are on the way, and by the will of Allah we will have unfettered access to wherever we want to attack. We have more than 100 men who are willing to lay down their lives for the cause of Allah.” The blast at about 11 a.m. left a gaping hole in the compound, which houses about 400 people working for 26 U.N. humanitarian and development agencies. It’s not clear how many were present, but dozens were injured .This marks the first attack on the U.N. by militants in Nigeria. Past attacks by Boko Haram, a group that models itself on the Afghan Taliban, have been launched on national government targets, mainly in the north. The largest previous bombing, of the police headquarters in Abuja in June, killed six.
