The hundreds of kidnapped girls missing in Nigeria may have been separated, according to United States intelligence officials. A team of seven U.S. military members will arrive Friday to assist in the Nigerian rescue efforts, assisted by Britain, France, and China. The kidnappers, a militant group called Boko Haram, have continued their terror spree, killing at least 310 people in a border area on Monday. "I believe the [kidnapping] of these girls will be the beginning of the end for terror in Nigeria," President Goodluck Jonathan told a plenary at the World Economic Forum on Thursday.
