The FBI says a joint terrorism task force made up of federal and local authorities has arrested two Southern California men following an investigation.

FBI spokeswoman Laura Eimiller says one man was taken into custody at Los Angeles International Airport and another was arrested in Anaheim on Thursday.

Eimiller said Friday that the case is terrorism-related but declined to give further details about the men and why they were arrested.

They are expected to be charged Friday in federal court in Santa Ana.

The task force includes the FBI, the Anaheim Police Department and the Orange County Sheriff's Department.
