Abuja (Nigeria): At least 200 people, mostly women and children displaced by violence in northeastern Nigeria, were abducted by Islamic extremists while they were searching for firewood near the border with Chad, the United Nations office in Nigeria said late Wednesday. The victims had left several displacement camps to look for firewood in Borno state’s Gamboru Ngala council area when they were ambushed and taken hostage, the UN said, in the latest attack in the conflict-hit region where frequent abductions and killings limit movement.Abuja (Nigeria): At least 200 people, mostly women and children displaced by violence in northeastern Nigeria, were abducted by Islamic extremists while they were searching for firewood near the border with Chad, the United Nations office in Nigeria said late Wednesday.
