Security Experts Dispute Authorities Claims Over Nigerian Schoolboy Abductions Timothy Obiezu ABUJA, NIGERIA - Nigerian security experts are casting doubt on the claim by authorities that tensions between farmers and cattle herders led to the recent wave of kidnappings in the northwestern state of Katsina. More than 300 schoolboys were abducted earlier this month but later released. Timothy Obiezu reports from Abuja. Authorities in Katsina initially blamed the mass abduction of 344 schoolboys on gangs of bandits who have kidnapped other people for ransom in the northwestern Nigerian state. Then officials reversed course, tying the abductions to cattle herders at odds with farmers about how to use the land. .
