Tamaulipas is considered one of the most violent states in Mexico, due to the presence of criminal organizations dedicated to migrant smuggling, drug trafficking and other illicit activities.

In May, military soldiers were caught on video executing five alleged members of a cartel in the border town of Nuevo Laredo.

Footage showed the gunmen's pickup truck crashing into the wall of a store before the military truck that was in pursuit of them rammed the vehicle.

The men were forced out of the pickup, beaten, dragged across the dirt-covered ground, forced to kneel facing the wall and later shot.

The soldiers tried to cover-up the scene by reporting that an infantry had been attacked by members of the Cártel del Noreste (Northeast Cartel). They said that the  troops were inspecting a pickup truck that was carrying the five victims. During the search, they said that the suspects tried to recover their weapons and were killed in a crossfire. 

In March, four Americans were kidnapped in that state, two of whom were killed and two rescued, in an incident that caused tension between the governments of the two neighbor nations.
