Mexican authorities say they have intercepted an overcrowded truck carrying 64 migrants in a northern state and arrested the driver and another person who were transporting them.
The National Security Commission says in a statement that the discovery came after agents scanned the vehicle. When federal police stopped the truck, they heard voices and pounding from inside and immediately opened it.
Two migrants were treated for lack of oxygen.
The commission said Thursday that the people in the truck were 40 Guatemalans, 13 Salvadorans, 2 Ecuadoreans and 2 Dominicans. Twenty-two were minors.
The truck was stopped along the Matehuala-Saltillo highway in Nuevo León state, south of the industrial city of Monterrey.
