Mexico will suspend its plan to distribute maps to migrants wanting to cross the U.S. border illegally, but an official said Thursday the decision was not made because of American pressure.

Miguel Angel Paredes, spokesman for the federal Human Rights Commission, said the decision was made because human rights officials in border states expressed concern that the maps would show anti-immigrant groups where migrants likely would gather.

On Wednesday, U.S. Homeland Security Secretary Michael Chertoff said the United States opposed the plan "in the strongest terms."
