President Donald Trump has declared Nigeria a “Country of Particular Concern,” citing what he described as an “existential threat” to Christianity in the West African nation.

The declaration, announced Friday via his Truth Social account, comes amid mounting reports of violence against Christians in Nigeria. Trump accused radical Islamist groups of orchestrating widespread killings, describing the situation as a “mass slaughter” that demands immediate action.

“Christianity is facing an existential threat in Nigeria. Thousands of Christians are being killed. Radical Islamists are responsible for this mass slaughter. I am hereby making Nigeria a ‘Country of Particular Concern’ — but that is the least of it,” Trump wrote.

He called on Congressman Riley Moore, House Appropriations Committee Chairman Tom Cole, and others to urgently look into the situation and report their findings.

“When Christians, or any such group, are slaughtered as is happening in Nigeria, something must be done,” Trump added. “The United States cannot stand by while such atrocities are happening in Nigeria and other countries. We stand ready, willing, and able to save our great Christian population around the world.”

The move marks one of Trump’s strongest statements yet on religious persecution in Africa and could signal a shift in U.S. policy toward Nigeria’s escalating security crisis.
