Boko Haram: we killed people of Baga because our lord ask us to in his book.

The confirmation from Boko Haram leader Abubakar Shekau came as no surprise after multiple eye-witness accounts of the attack on Baga, which is thought to have killed hundreds, if not more.

But Shekau claimed that the January 3 attack, in which large parts of Baga were burnt to the ground and at least 16 surrounding settlements were razed, was only a prelude to further attacks.

"We killed the people of Baga. We indeed killed them, as our Lord instructed us in His Book," Shekau said in the 35-minute message, which was posted on YouTube.
