About 200 girls are still missing in Nigeria amid reports that they are being sold as child brides for $12 dollars a piece.
They were were kidnapped 16 days ago by al-Qaeda-linked Boko Haram, one of the most brutal terrorist groups in the world.
The girls' parents are devastated and beyond frustrated.
Nigerians took to the streets Thursday to demand the government do more to rescue the girls. And many of those protests have been spurred by social media - many using the Twitter hashtag #BringBackOurGirls to spread the word. At one point Thursday, the hashtag was used at a rate of nearly 20,000 tweets per hour.
