MEXICO CITY — Three state police officers and four suspected drug cartels were killed in a shootout in the northern Mexican border state of Tamaulipas across the border from Texas, officials said Wednesday.

Five other police officers were injured in the series of clashes along highways around the city of San Fernando, Tamaulipas.

Gunmen from drug cartels set up roadblocks and attacked police patrols in the area on Tuesday, and later in the day again attacked a funeral convoy of cars carrying the body of one of the victims of the first attack.

The state security spokesman’s office confirmed the deaths Wednesday, but there was no immediate information on the condition of the injured officers.

San Fernando is a city halfway between the state capital, Ciudad Victoria, and the border cities of Matamoros and Reynosa.

San Fernando was the scene of some of the worst violence of Mexico’s drug war between 2010 and 2011. In those years, gunmen from drug cartels massacred 72 migrants, many from Central America and killed approximately 122 bus passengers. Those victims were pulled from passing buses and forced to fight to the death with the sledgehammer.

Tamaulipas has long been dominated by the Gulf cartel and the old Zetas cartel, now known as the Cartel del Noreste.

Also Wednesday, suspected cartel suspects from another border state, Sonora, killed a detective and wounded two others in an attack Wednesday in which the suspects rammed a police vehicle.

The matchup played out Wednesday morning on a road leading to the border town of Sasabe, west of Nogales, Arizona. A Mexican marine was also injured in the attack. All the injured were listed in stable condition.

Authorities were chasing an SUV driving with its lights off on a rural road when the suspects first rammed detectives’ patrol vehicles and then a unit of Mexican riflemen before opening fire. Marines and detectives returned fire, killing three suspects.

The area is a hub for smuggling migrants and drugs.
