Are Christians being persecuted in Nigeria as Trump claims?

US President Donald Trump's claims of Christian persecution in Nigeria have sparked controversy, with some alleging Islamist militants target Christians. While data suggests violence against Christians, the narrative has been difficult to verify. Concerns have been raised by US politicians, including Senator Ted Cruz, about the mass killing of Christians in the country. However, other research groups like Acled provide differing figures on political violence in Nigeria, indicating that Christians are not the sole target of attacks.
