Two years after the abduction of nearly 300 Chibok schoolgirls by Boko Haram militants in northeast Nigeria, some parents are still hoping their daughters will one day be rescued.
But some church leaders there are concerned that the authorities have not done enough to rescue the girls, who were ages 16 to 18 at the time of the kidnapping on April 14, 2014. About 50 of the girls escaped, but 219 remain missing.
