Christians are being hunted and killed in Northern Nigeria—and the world is looking away. Siege: The Killing of Christians in Northern Nigeria is a searing narrative and documentary account of what the author describes as an ongoing genocide against Christian communities across the North. Through survivor testimonies, historical background, human rights reports, and powerful photographs, the book traces how violence long dismissed as "farmer–herder clashes" or "banditry" has become a deliberate campaign of religious cleansing. From the Danish cartoon riots in Maiduguri in 2006, to church burnings, massacres of pastors and congregations, and the systematic destruction of villages, Siege shows how Christian populations have been targeted, displaced, and erased while authorities and much of the international community struggled—or refused—to name the crime. Drawing on the voices of diplomats, church leaders, traditional rulers, and investigators such as former mayor Mike Arnold, it argues that these are not isolated incidents but a coordinated effort to de-Christianise entire regions. Written as both a chronicle and a cry for help—echoing the biblical appeal, "Come to Macedonia and help us" (Acts 16:9)—this book calls on Christians, human rights defenders, policymakers, and all people of conscience to confront the reality of the killings and to act before more lives and communities are lost.
