Mexico City (AFP) - Mexican authorities detained more than 500 undocumented migrants over the weekend, mostly Central Americans trying to reach the United States, many of them risking their lives, officials said.
Many of the migrants, who were detained in six different operations, were being trafficked by smugglers in unventilated trucks with no food or water.
More than 200 others were found crammed into six "safe houses" used by criminal gangs in the state of Tamaulipas, which borders the United States.
The detentions come as immigration across the southern US border is at the center of a political firestorm in Washington.
