An Uzbekistan national, Fazliddin Kurbanov, is facing terrorism charges Friday in Idaho. Federal agents arrested Kurbanov Thursday in Boise.
A federal grand jury has already indicted him for allegedly providing support and resources to the Islamic Movement of Uzbekistan, a known terrorist group.
The IMU was started in the 1990s with the stated aim of overthrowing the Uzbek regime and establishing an Islamic government, but its goals have expanded to creating a broader Islamic caliphate across all of Central Asia.
Authorities say Kurbanov was involved in terrorist activities in Idaho and Utah.
He's accused of distributing information about explosives, bombs and weapons of mass destruction. And investigators say he possessed a destructive device during November of last year.
Kurbanov is a U.S. citizen.
