Boko Haram is abducting Christian women, converting them to Islam on pain of death and then forcing them to marry its fighters, reports Reuters.

Reuters tells the story of 19-year-old Christian Hajja, who was abducted by the Islamist group in July and was then forced to work as their slave.

Hajja converted to Islam, cooked for the men, carried ammunition during an attack on a police outpost and was about to be married to one of the insurgents when she managed to escape.

“If I cried, they beat me. If I spoke, they beat me,” Hajja told Reuters. “They told me I must become a Muslim but I refused again and again. They were about to slaughter me and one of them begged me not to resist and just before I had my throat slit I relented. They put a veil on me and made me read from the Quran.”
