Buhari warns US over Boko Haram, more than 50 dead in attacks

Twin suicide attacks in Maroua, northern Cameroon, killed at least 11, while some 42 lost their lives in a series of blasts at two bus stations in Gombe, northeast Nigeria.

The latest atrocities came after Boko Haram released a new video on Twitter, maintaining they were not defeated and vowing: “We will be coming from where you never expected, stronger than before.”

A new, five-nation force – from Nigeria, Niger, Chad, Cameroon and Benin – is due to deploy by July 30 to take on the Islamic State Group-allied militants, whose six-year insurgency has left at least 15 000 dead and increasingly threatened regional security.

The attack in Cameroon saw two girls aged “under 15” bomb the central market in Maroua, as well as the adjoining Hausa neighbourhood, said regional governor Midjiyawa Bakari.
