Wall Street Journal: Police in Mexico's southern Chiapas state found 513 migrants inside two trailer trucks bound for the United States, and said they had been transported in dangerously crowded conditions. Some of the immigrants were suffering from dehydration after traveling for hours clinging to cargo ropes strung inside the containers to keep them upright as the trucks bounced along from the Guatemalan border, and allow more migrants to be more crammed in on the floor.
