The Islamic terrorist group, Book Haram has killed another of the three ICRC aid workers who were kidnapped in Rann March this year. Hauwa's death, as reported by the cable, came 24 hours after the ultimatum given to the government.
It is the second murder after Hussaini Ahmed was killed by the sect in September following similar threats. Also, the Christian girl held in captivity for refusing to renounce her faith – Leah Sharibu, has been declared a slave by the sect who have vowed to do whatever they wish with her.
Book Haram, Operating majorly in the Northern Part of Nigeria and some parts of West Africa, has committed some of the worst atrocities known to present day Nigeria with a casualty figure that surpasses that of ISIS.
The governments failure to intervene has been heavily criticized as the politicization of such sensitive issues take centre stage while Christians and even Muslims who oppose the sect remain an endangered species.
