Reunited: A girl who had been kidnapped by Boko Haram celebrates with family members during a church service held in Abuja, Nigeria, on Sunday. Twenty-one girls were released Thursday and flown to Abuja, Nigeria’s capital, but it took days for their parents to arrive. The families came from the remote northeastern town of Chibok, where nearly 300 girls were kidnapped in April 2014 in a mass abduction. Dozens of schoolgirls escaped in the first few hours. After last week’s release, 197 remain captive.
