The girls in the school dorm could hear the sound of gunshots from a nearby town. So when armed men in uniforms burst in and promised to rescue them, at first they were relieved.
"Don't worry, we're soldiers," one 16-year-old girl recalls them saying. "Nothing is going to happen to you."
"They ... started shouting, 'Allahu Akhbar,' (God is great)," the 16-year-old student said. "And we knew."
What they knew was chilling: The men were not government soldiers at all. They were members of the ruthless Islamic extremist group called Boko Haram. They kidnapped the entire group of girls and drove them away in pickup trucks into the dense forest.
Three weeks later, 276 girls are still missing. At least two have died of snakebite, and about 20 others are ill, according to an intermediary who is in touch with their captors.
