KADUNA — Gunmen have killed six people in a village in Nigeria's northern Kaduna state, a government official said Thursday, in a region with a history of inter-ethnic violence. The attack late on Wednesday was in a village in the Zango Katak region in Kaduna state, witnesses said, an area at the heart of post-election violence last April that left hundreds dead and thousands displaced. Largely Muslim Northern Nigeria has been beset by violence for more than two years and it worsened when President Goodluck Jonathan, a Christian southerner, won the election last year. “ — Reuters
