Mexican migrants bound for US discovered

Police in Mexico's southern Chiapas state have found 513 migrants crammed in dangerously crowded conditions inside two trucks bound for the US.

Some of the immigrants were suffering from dehydration after travelling for hours inside the containers. The trucks had holes punched in the containers, but migrants said they lacked air and water. The trucks came from Guatemala and were bound for the central city of Puebla, where the migrants said they would be loaded aboard a second set of vehicles for the trip to the US border.
