MISSION - CHANNEL 5 NEWS is exposing what appears to be a Mexican military incursion into the United States. It was all caught on camera. We froze surveillance video taken at the Anzalduas International Bridge.

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.
