President Donald Trump on Saturday said he has asked the Defense Department to prepare for possible "fast" military action in Nigeria if the West African nation fails to crack down on the killing of Christians, Reuters reported.

The U.S. government will also immediately stop all aid and assistance to Nigeria, Trump said in a post on Truth Social. If the United States sends in military forces, it would go in "'guns-a-blazing,' to completely wipe out the Islamic Terrorists who are committing these horrible atrocities," Trump wrote, without providing any evidence of specifics about the treatment of Christians in Nigeria.

Trump called Nigeria a "disgraced country" and warned its government must move quickly. "If we attack, it will be fast, vicious, and sweet, just like the terrorist thugs attack our CHERISHED Christians!" he wrote, according to Reuters.
