WEST PALM BEACH, Fla. (AP) — President Donald Trump said Thursday night that he’d launched a “powerful and deadly” U.S. strike against Islamic State forces in Nigeria, after spending weeks accusing the West African country’s government of failing to rein in the persecution of Christians.

“Tonight, at my direction as Commander in Chief, the United States launched a powerful and deadly strike against ISIS Terrorist Scum in Northwest Nigeria, who have been targeting and viciously killing, primarily, innocent Christians, at levels not seen for many years, and even Centuries!” the president posted on his social media site.

His post did not include information about how the strike was carried out, nor what effects it had. But the U.S. Africa Command posted on X that it had “conducted a strike at the request of Nigerian authorities in Soboto State killing multiple ISIS terrorists.”

“Lethal strikes against ISIS demonstrate the strength of our military and our commitment to eliminating terrorist threats against Americans at home and abroad,” its post said.

The Defense Department did not immediately answer requests for comment.

In response to Trump’s previous criticisms, Nigeria’s government says that people of many faiths, not just Christians, have suffered attacks at the hands of extremists groups.

Still, last month, Trump said he’d ordered the Pentagon to begin planning for potential military action in Nigeria following the claims of Christian persecution. The State Department has also announced it would restrict visas for Nigerians and their family members involved in mass killings and violence against Christians in the West African country.

And the U.S. recently designated Nigeria a “country of particular concern” under the International Religious Freedom Act.

“I have previously warned these Terrorists that if they did not stop the slaughtering of Christians, there would be hell to pay, and tonight, there was,” Trump wrote in his Christmas night post.

He said that U.S. defense officials had “executed numerous perfect strikes, as only the United States is capable of doing” and added that “our Country will not allow Radical Islamic Terrorism to prosper.”

Nigeria’s population of 220 million is split almost equally between Christians and Muslims. The country has long faced insecurity from various fronts including the Boko Haram extremist group, which seeks to establish its radical interpretation of Islamic law and has also targeted Muslims it deems not Muslim enough.

But attacks in Nigeria often have varying motives. There are religiously motivated ones targeting both Christians and Muslims, clashes between farmers and herders over dwindling resources, communal rivalries, secessionist groups and ethnic clashes.
