(BBC News) Female suicide bombers in Nigeria are now carrying babies to avoid detection in their attacks, authorities warn.
An attack in the town of Madagali on 13 January saw two women detonate their devices, killing themselves, two babies, and four others.
They had passed a vigilante checkpoint, mistaken for civilians because they were carrying infants.
