Hundreds of people marched in Nigeria on Tuesday to press for a greater response to a mass kidnapping of young girls. The Islamist militant group Boko Haram is suspected of abducting about 230 schoolgirls during a night raid in a northeastern area two weeks ago. Some managed to escape, but more than 200 remain missing. Dubbed by organizers a “Million Woman March,” the demonstrators carried signs reading “Bring Back Our Girls.”

Halita Aliyu: “I personally believe that not enough is being done to rescue our daughters. Please recollect like two, three months ago, 25 girls were abducted from Konduga. Because the nation has not risen in unison to do something about those 25 girls abducted in Konduga, it is now possible to abduct another 200-plus. Next time, maybe it will be more. Each and every one of us needs to do something to arrest the unpleasant developments that are happening in the country, especially in the northeast.”

A local human rights group is claiming the girls have been sold off, forced to marry their abductors, and taken across the border to Cameroon and Chad. The report has not been verified. The mass kidnapping is seen as one of the most shocking attacks in the Boko Haram’s five-year militant campaign, which has left thousands of people dead.
