Nigeria’s extremist Muslim group leader released a video threatening to sell 276 teenage girls, abducted from a school in the remote northeast three weeks ago.

The videotape was received Monday. The militant group is called Boko Haram. The leader Abubakar Shekau claimed credit for abducting those schoolgirls on the night of April 14. 

"I abducted your girls," said Shekau, according to CBS News."By Allah, I will sell them in the marketplace." 

The hour-long video started with militants holding rifles and shooting in the air. 

People are protesting throughout the country, expressing their outrage to the mass abduction and the failure by the government so far to rescue the girls.
