Two years on, Chibok schoolgirls are still missing

Thursday marks exactly two years since almost 300 schoolgirls were abducted by Boko Haram militants from the town of Chibok, in Nigeria. Families, friends and campaigners refuse to let the girls’ plight be forgotten and march in their memory.
For the first time since 2014, a video showing proof of life of some of the girls has been seen by a handful of distraught parents. The footage adds pressure on Nigerian negotiators still trying to secure the captives release, but for Chibok families it’s a bittersweet glimpse of familiar faces.
In Juba, the atmosphere is edgy ahead of the return of the rebel leader. Some of Riek Machar’s fighters have set up camp around the south Sudanese capital but accuse the army of President Salva Kiir of having boosted its numbers despite a demilitarisation agreement.
