The FBI says it disrupted a New Year’s Eve attack plot in North Carolina, arresting an 18-year-old who allegedly pledged loyalty to the Islamic State group. Christian Sturdivant is charged with attempting to provide material support to a foreign terrorist organization. Authorities say he shared plans with an undercover FBI employee to use knives and hammers to carry out the attacks. Sturdivant was arrested Wednesday and remains in custody. An attorney representing him did not respond Friday to requests seeking comment. The investigation began last month after authorities linked Sturdivant to a social media account that posted content supportive of IS.
