Trump targets ISIS in Nigeria amid warnings Sahel region is becoming 'epicenter of terrorism'

While the Christmas strikes zeroed in on ISIS militants, there are a number of violent extremist organizations operating in Africa's Sahel region, where U.S. officials claim they are continuing to grow in influence and strength as violence surges there. 

"In Sokoto, it has carried out attacks against both government forces and civilians, representing just one jihadist group operating in Nigeria," Weiss said in a statement Thursday.

"In addition to IS Sahel, there is also IS West Africa Province, which supports and coordinates with IS Sahel in NW Nigeria; the so-called Boko Haram; and the Al-Qaeda groups of Ansaru and the Group for Support of Islam and Muslims, which, like IS Sahel, is a group mainly based in Mali and Burkina Faso, but in recent years have also made inroads into Nigeria that has effectively made the Sahelian and Nigerian conflicts one large conflict," Weiss said. 

Meanwhile, the Sahel region, which primarily includes Nigeria, Niger, Burkina Faso and Mali, is ripe for terrorist activity, and U.S. officials have long cautioned about the threat that these groups pose to the U.S. homeland.

"It is the flashpoint of prolonged conflict and growing instability. It is the epicenter of terrorism on the globe," Langley said. 

"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 said on Thursday in a post on Truth Social. "The Department of War executed numerous perfect strikes, as only the United States is capable of doing."
