The reported arrest of Mahmoud Adam in Plateau State has drawn attention in Washington, with US Congressman Riley Moore describing the development as evidence of progress in security cooperation between Nigeria and the United States.

Moore, a Republican member of the US House of Representatives, reacted to the development in a post on X on Saturday. He welcomed the reported detention of Adam and described him as a radical Islamic Fulani terrorist leader allegedly connected to attacks against Christians in Nigeria.

The congressman said the development represented encouraging news for Christians affected by violence, while crediting Nigerian authorities for the reported arrest.

According to Moore, the development also indicated that the security partnership between Abuja and Washington was beginning to produce results.

“The arrest of Mahmoud Adam … is proof that the US-Nigeria Security Cooperation agreement is bearing fruit,” Moore said in his post.

He also credited the US Congress and the administration of President Donald Trump for their efforts to address attacks against Christians in Nigeria, calling for continued action to protect communities affected by terrorism.

Reports cited by US media indicate that Adam was arrested on September 12 at his compound in Plateau State. He has been described in reports as a prominent Fulani community figure, alongside allegations linking him to a militia network accused of violence in the Middle Belt.

However, the allegations surrounding Adam’s alleged role in attacks remain subject to official clarification. Moore’s description of him as responsible for the deaths of numerous Christians is an allegation made by the US lawmaker and has not been independently established in the available Nigerian official information.

The development comes as Nigeria and the United States continue to deepen security cooperation, with Moore having previously engaged Nigerian officials over counterterrorism and the protection of communities affected by insecurity.
