ABUJA, Nigeria (AP) — A gunbattle between rebels and Nigerian security forces has left 10 police officers dead in a remote part of the country’s conflict-battered north, authorities said Tuesday. The rebels were heavily armed and riding on motorcycles when they were intercepted by security forces, said Usman. They were seen close to the border with Zamfara state, where armed gangs who frequently raid Nigerian towns and villages are concentrated. “Tragically, we lost 10 gallant police personnel in the engagement, while two others sustained injuries and are receiving medical attention,” the police spokesman said. Dozens have been killed in recent weeks across the north, and security forces are often targeted.
