Sources say that the Zetas are out of Reynosa tonight.
They've moved about 150 miles west to Nuevo Laredo. Intelligence sources say that the group wants to take over the city and make it their base of operations.
The U.S. Consulate General's office has already confirmed a gunbattle in Nuevo Laredo. It's happening near Boulevard Colosio and the city's zoo. The consulate general's office is telling all U.S. citizens to take shelter until the fighting stops.
Sources say that the Zetas are already calling in reinforcements. We're told 700 Zetas from around Mexico are joining the 500 already brought to the area last week.
The Gulf Cartel also called in reinforcements last week. They joined forces with two rival cartels, La Familia Michoacana (LFM) and the Sinaloa Cartel.
Our sources tell us the Sinaloa Cartel and LFM have a deep hatred of the Zetas. They could also benefit by getting a cut of the Valley's drug smuggling business.
It was a rough week for the border, following an explosion of shootouts and grenade attacks in northern Tamualipas.
Violence was reported in border cities like Valle Hermoso, Reynosa, Guerrero, Miguel Aleman, Ciudad Mier, and Valadeces. According to the Mexican military sources, last week's violence left at least 23 people dead.
Our sources tell us it was triggered when a Gulf Cartel member murdered a Zeta leader on January 18. The Zetas demanded the Gulf Cartel hand over the killer.
When that didn't happen, the Zetas kidnapped 16 Gulf Cartel members in Miguel Aleman. We're told that led to the shootouts up and down the border.
