A top military official in Nigeria has said officials have located the nearly 300 schoolgirls abducted by Boko Haram, but will not risk going in with force to attempt a rescue. Air Marshal Alex Badeh reportedly made the remarks in the capital Abuja as demonstrators there rallied to demand the girls’ return. They have been missing for six weeks. U.S. military specialists have been participating in the search. Over the weekend, Nigeria was rocked by further violence, including an attack by gunmen in the northeast that killed 20 people at a market.
