A week ago, a spiralling violence has escalated in Nigeria as Boko Haram group unleashed series of recent attacks.
Boko Haram is a local terrorist group professing allegiance to Al Qaeda. Boko Haram militants attacked several churches on Christmas Day, killing dozens of worshippers.
Secretary-General Ban Ki-moon strongly condemned today the deadliest attacks in Nigeria’s Kano.
Mr. Ban said he was appalled at the frequency and intensity of recent attacks in Nigeria, which demonstrate a wanton and unacceptable disregard for human life. He voiced concerned and his solidarity with the Government and people of Nigeria. He expressed his hope for swift and transparent investigations into the attacks to ensure perpetrators are brought to justice.
Boko Haram, which aims to install strict Shariah, or Islamic, law across Nigeria, has vowed to keep killing Christians in the multiethnic country.
Boko Haram, which loosely translates from the local Hausa language as “Western education is forbidden”, has been behind a string of attacks in recent years.
