Mexican army soldiers freed 11 abducted Central American migrants and seized an arsenal in two separate operations in the northeastern state of Tamaulipas, military officials said.
The kidnap victims were freed in the city of Tampico thanks to an anonymous tip, the command headquarters of the 4th Military Region said in a statement.
Seven of the freed migrants are of Salvadoran origin, two are Honduran and two are Guatemalan, according to authorities, who said three purported kidnappers were arrested and a vehicle, a rifle, a handgun and a property were seized.
Tens of thousands of Central Americans undertake the hazardous journey across Mexico each year on their way to the United States.
The trek is a dangerous one, with criminals and corrupt Mexican officials preying on the migrants.
Separately, soldiers found a safe house in the border town of Rio Bravo, Tamaulipas, - located across the Rio Grande from Donna, Texas - that was being used by criminal gangs as a place to stash and repair weapons.
They seized 14 rifles, three handguns, three grenade launchers, eight rifle grenades, 1,859 ammunition clips, 13,660 rounds of ammunition and tactical and communications gear in the operation.
