“A Boko Haram attack has killed hundreds in Nigeria’s northeast, multiple sources have said, as police offered $300,000 for information leading to the rescue of more than 200 schoolgirls held hostage by the armed group. Zanna said the town had been left unguarded because soldiers based there had been redeployed north towards Lake Chad in an effort to rescue more than 200 girls kidnapped by Boko Haram on April 14.”
