Security officers have once again barricaded the Bring Back Our Girls group from 

gaining access into Aso Rock. The advocacy group today went on a silent march

 to the Presidential Villa, to advocate for the release of the Chibok schoolgirls

 that were kidnapped by Boko Haram terrorists, 869 days ago. See more photos
