Some sicko Muslim group named "Boko Haram" (which means - Western education is forbidden) kidnapped some girls from their boarding school in Chibok, Nigeria. They feel that Western education is the cause of the problems in Nigeria. They have a history of killing students. They also have a history of kidnapping girls and using them as sex slaves. They are threatening to sell the girls.
The reports say 329 were kidnapped and 53 escaped. We can not be sure how correct these numbers are.
