Boko Haram Islamic militants have kidnapped at least 2,000 girls and women since the start of last year, turning them into cooks, sex slaves and fighters, and sometimes killing those who refused to comply, Amnesty International said on Tuesday.
The human rights group's 90-page report based on dozens of interviews with witnesses and escaped abductees comes a year after the group seized more than 200 schoolgirls from Chibok, a community deep inside an area of northeastern Nigeria the fighters claimed as their caliphate.
The kidnapping, and a video showing the captured girls dressed in dark hijabs soon afterward, provoked international outrage. But the majority are still missing despite Western pledges to help track them down and a Chadian attempt to broker their release.
