Parents of missing Chibok schoolgirls gather on Tuesday to mark one year since 219 schoolgirls were kidnapped by Boko Haram in the northeastern Nigerian city of Chibok. Two schoolgirls who were among hundreds kidnapped by the Nigerian terror group Boko Haram were at the U.S. Capitol on Wednesday pleading for renewed attention to their fellow students still missing a year later despite an international "Bring Back Our Girls" campaign. Saa, 19, and Patience, 18, who managed to escape from the Islamist extremists, recounted the experience of being taken in the middle of the night from their boarding school in Chibok before jumping out of moving vehicles and fleeing through a forest. They begged a shepherd for help, and eventually made their way home. Patience, who was injured in the escape, spent the next two months on crutches.
