Boko Haram leader warns mass murder of hundreds in Baga is just ‘tip of the iceberg’

Boko Haram has claimed responsibility for the mass killings in the north-east Nigerian town of Baga in a video where he warned the massacre “was just the tip of the iceberg”.

As many as 2,000 civilians were killed and 3,700 homes and business were destroyed in the 3 January attack on the town near Nigeria’s border with Cameroon, according to estimates by Amnesty International.
