The FBI arrested a total of six men, according to family members, who said they didn’t know why their sons were arrested.

Authorities are planning a press conference Monday morning to provide more information.

Federal authorities have been investigating the departures of about 15 young people from the Twin Cities who allegedly traveled to Syria to support the terrorist group ISIS over the past year or so.

Updates to follow.


Update 10:57:

From CNN:

The FBI has arrested at least six men in what officials called an ISIS-inspired terror plot.

Details were scant Sunday night, but federal law enforcement officials told CNN the men were arrested in Minnesota and California in a sting operation.

There was never a direct threat to the public, the sources said. The plot was controlled by the FBI, which is a common tactic in terrorism investigations.
