Military U.N. vehicles have been spotted in Virginia, shocking motorists and sparking conspiracy theories.

The white trucks, equipped with large off-road tires, were seen being transported on Interstate 81 on Friday. They appear to be Alpine Armoring's Pit-Bull VX SWAT Truck models.

Jeff Stern posted photos of the vehicles on Facebook, writing: 'Can't begin to tell you how many of these I passed today on 81 near Lexington VA. Interesting times ahead!'

Fernando Johnson questioned online: 'Tactical Vehicles, with bullet proof glass? Whatever could those be for, and why are UN vehicles here, in THIS country?!'

Meanwhile, Vincent Sammons noted on Facebook: 'They are sealed against gas too.'

Another online commenter said: 'We have U.N. vehicles being shipped on U.S. highways. One has to wonder why?'

Bobby Wayne Guinn posted on Facebook that he had witnessed similar scenes in Texas.

He wrote: 'Wondering why 30 United Nations vehicles, fully loaded with combat-prepared troops, were driving down our highway in Dallas, Texas.'

His post sparked website Liberty is viral to ask: 'Are these U.N. troops here preparing for economic collapse in America? Is this related to Iran ships approaching the U.S. border?' while Alex Jones posted a video warning of the 'U.N. takeover of America.'
