Mexican legislators are calling on their Latin American counterparts to join them in opposing a proposed barrier along the U.S.-Mexican border.

Heliodoro Diaz, who presides over Mexico's House of Representatives, has sent a written request to several regional legislatures as well as to parliaments in Spain and Portugal. Mr. Diaz says opposing the wall would be "an act of unity among Ibero-American legislatures."

The U.S. House of Representatives approved a measure earlier this month to construct security fencing along the U.S.-Mexican border in an effort to curb illegal border crossing. The measure would also reclassify illegal entry into the United States as a crime, instead of a civil offense, as at present.
