The National Intelligence Agency (NIA) is a Nigerian government division tasked with overseeing foreign intelligence and counterintelligence operations.
Fulfilling one of the promises made in his first national address as president, in June 1986, Ibrahim Babangida issued Decree Number 19, dissolving the National Security Organization (NSO) and restructuring Nigeria's security services into three separate entities under the Office of the Co-ordinator of National Security.
