Boko Haram 'leader' claims responsibility for Baga massacre

A man claiming to be the leader of Islamist group Boko Haram has appeared in a video to claim responsibility for a deadly attack on the Nigerian town of Baga.

The man said to be Abubakar Shekau said the attack "is just the tip of the iceberg" as he warned that the group has enough weapons to "annihilate Nigeria, not to mention Cameroon".

Local officials put the death toll in Baga as high as 2,000 but the Government said 150 people were killed when insurgents stormed a military base in early January.

The bearded man is surrounded by masked fighters in the video, who show off an array of weapons allegedly taken from the base during the attack.
