Nigeria's Buhari tells released Chibok girls he will "redouble" rescue efforts

By Felix Onuah ABUJA (Reuters) - Nigeria's President Muhammadu Buhari on Wednesday told a group of 21 girls released by Islamist militants last week that he will "redouble" efforts to bring home about 200 still missing after the kidnapping in Chibok in 2014. About 270 girls were seized at their school in northeastern Borno state, where Boko Haram has waged a seven-year insurgency, killing thousands of people and displacing more than 2 million. "We shall redouble our efforts to bring the rest back home," Buhari said.
