Chibok girls: One year on from Nigeria kidnappings

On 14 April 2014, 279 schoolgirls were kidnapped by the Islamist militant group Boko Haram in Chibok, northern Nigeria.

The government's slow response in finding the missing girls caused a global uproar. Many protests took place and an online campaign went viral.

But a year later 219 girls are still missing.

BBC News looks back at the past 12 months.
