The Nigerian army is still combing Bama and gatheringinformation from its citizens. Dozens of women that had beenforced to marry Boko Haram militants were killed by their'husbands' before a battle, witnesses said. One witness, a39-year-old mother of three, Sharifatu Bakura, was spared fromsuch a marriage because she was visibly pregnant, despite herhusband, a combatant, having been killed by the militants fourmonths ago. She affirmed that the Islamist group was aware ofthe imminent military attack and feared that the 'wives' wouldbe given to state troops or other non-believers.
