The Lotsu-Piri of Nigeria, numbering approximately 40,000 people, are No Longer Unreached. They are a Tsobo people, called Pire by their neighbors, long established in Nigeria's southeastern Muri Mountains, whose hilltop hamlets were once enclosed by defensive dry-stone walls with a single entrance gate, organized into four sections. They mostly adhere to Protestantism and Tso is their primary language.
