What you see is the international boundary that separates the United States from Mexico and what authorities on this side of the border seem to think is a truck packed with armed men crossing into the United States. The video clearly shows a large military-transport vehicle drive north on the Anzalduas bridge over the international boundary.
We counted at least a dozen armed men in the back of the truck. The vehicle travels down the bridge toward the U.S. Customs checkpoint. Its driver makes a U-turn just before reaching the lines of cars there. It then starts back south toward Mexico. The men pull over and search a vehicle for a few minutes then resume their trek south. The presumed soldiers then cross back over the boundary toward Mexico.
They are in U.S. territory for about 10 minutes. We're taking a closer look at the vehicle they stopped on the bridge and what U.S. authorities have to say about this apparent incursion.
