Attorney General Eric Holder says he'll send FBI agents into Nigeria to aid in the rescue of more than 200 Nigerian girls being held hostage by terror group Boko Haram. John Kerry also proclaimed his support, saying, "we will do everything possible to support the Nigerian government to return these young women to their homes." Earlier Monday, self-proclaimed Boko Haram leader Abubakar Shekau said in a video that he will sell hundreds of kidnapped Nigerian girls. “I abducted your girls,” he said. "I will sell them in the market, by Allah.” Some of the girls have been reportedly sold as brides for as little as $12 in neighboring Chad and Cameroon. It's unclear if Nigeria will accept the offer of U.S. assistance.
