Protests mark third anniversary of Nigerian schoolgirls' mass abduction

Nigeria is marking three years since the mass abduction of nearly 300 schoolgirls by Boko Haram extremists amid anger that government efforts to negotiate their freedom appear to have stalled.

Activists are expected to rally in the capital, Abuja, and the commercial hub Lagos in an attempt to urge President Muhammadu Buhari's government to do more to free the nearly 200 schoolgirls who remain captive.
