Wielding machetes and poisoned-tipped arrows, mobs angered over the Nigerian presidential election rampaged through the city of Kaduna, which straddles the line between the country’s Christian south and Muslim north. The results of the vote in Africa’s most populous nation showed that the country’s Christian leader, Goodluck Jonathan, had won re-election. The outcome prompted Muslim rioters to burn houses, churches, and police stations. Christian mobs hit back almost immediately, according to news reports, in one instance tearing apart a home in search of a Koran to prove the owners were Muslim, then setting the dwelling ablaze. The violence in Kaduna and elsewhere in the north left more than 100 people dead.
