The mother of the Nigerian finance minister was taken from her home Sunday, according to officials. Kamene Okonjo, a professor, had been threatened recently, according to a spokesperson for her daughter, finance minister and anti-corruption crusader Ngozi Okonjo-Iweala. She was one of the top contenders for the position of managing director of the World Bank before Jim Yong Kim was appointed. Now officials fear her mother may have become the latest victim of the country’s multimillion-dollar kidnapping industry. At 82, Okonjo is a medical doctor and retired professor.
