At least 20 dead in Nigeria bombings KANO, Nigeria, Jan. 21 (UPI) -- The death toll in coordinated bomb attacks reached more than 20 in the northern Nigerian city Kano, witnesses said, and authorities imposed a 24-hour curfew. A journalist who had been covering the violence after a bombing, Nigerian Channels TV's Enenche Akogwu, 31, was fatally shot Friday outside the Kano Government House while on duty, Nigeria's P.M. News reported. The militant Islamist group Boko Haram claimed responsibility for the bombings, the latest attributed to violence in the mainly Muslim north recently. Targets of the bombings included police stations and the state police headquarters and gunfire could be heard in Kano, Nigeria's second-largest city, the BBC reported Saturday. The group, whose named means "Western education is forbidden," carried out the attacks because authorities had refused to release its members arrested in Kano, Boko Haram spokesman Abul Qaqa, told journalists in the northeastern city of Maiduguri. The group seeks to establish Sharia, Islamic law, in Nigeria and has been attacking Christians and animists living in the north. Police said seven casualties had been confirmed in the blasts but witnesses said they counted at least 20 bodies of victims on the streets and being loaded into wagons, the BBC said. The curfew will remain until further notice, officials said.
