A Kano based journalist shared this disturbing photo of a visibly mentally ill woman who is pregnant.Sir-Jalal-Falal wrote
It was a terrible moment when driving this morning and saw a woman with total mental disability but yet pregnant. I packed by the roadside to confirm what my eyes were seeing while heard some young boys called her "Yan Mata" literal meaning of "YOUNG LADY". How could this happened in a supposedly decent society for God's sake?
