Nigeria pledges to beef up security at camps after more than 50 die in attack

Nigeria's Vice President Yemi Osinbajo says security will be strengthened "in and around the internally-displaced people's (IDP) camps" following the killing of at least 56 people at a camp in Borno state, north-east Nigeria.

The bombers, both female, detonated their explosives while the camp's residents were queuing for rations.

They have been displaced by the Boko Haram insurgency in the area.

Mr Osinbajo says the measures should "guard against future occurrences".

The Dikwa camp, pictured earlier this month, is home to tens of thousands of displaced people
