Police say at least two of the seven suspects arrested for the fatal shooting of two Louisiana sheriffs deputies last Thursday are connected to the anti-government "sovereign citizen" movement.

According to WBRZ-TV, 28-year-old Kyle Joekel and 44-year-old Terry Smith had identified themselves as part of the movement, which was classified as a domestic terror group last year by the FBI.

Joekel and Smith, along with several members of Smith's family and other associates, were arrested following an ambush on authorities in LaPlace, Louisiana, about 25 miles west of New Orleans. Deputies Brandon Nielsen and Jeremy Triche were killed in the ensuing shootout. Two more deputies were wounded.
