Videos show fighting between cartel factions on the Mexico-US border

The recording location is 1.5 kilometers from the city of Donna, in the USA, near the Rio Grande. “This is possibly one of the most dangerous areas on the border,” Christopher Olivarez told Fox News TV channel.
In the images, it is possible to see groups shooting with large-caliber weapons. They also throw devices similar to explosives through car windows and shoot at other people, who flee the shots.
They don’t use ‘common weapons’, they use military weapons. If someone is passing through that border area, they could be hit.
