Mexico: 500 migrants found in trucks in Chiapas

The 513 migrants, from Latin America and Asia, were were found travelling in "inhumane" conditions, police said. Four people accused of smuggling the migrants were arrested, officials said.
The discovery, made in Mexico's southern Chiapas state, is one of the biggest cases of suspected human trafficking, police say. The migrants were discovered using X-ray equipment at a checkpoint, about to be smuggled illegally into the US, police said. They travelled for hours clinging to nets strung inside containers, according to the AP news agency.  Though there were holes for air punched in the floors of the containers, the migrants lacked air and water, they told AP. Police believe the foreigners had to pay $7,000 (£4,300) per person to the alleged traffickers to take them into the US. "It is the largest ever such operation to rescue illegal migrants travelling in inhumane conditions," a police spokesman told the AFP news agency.The trucks were stopped on a highway near the state capital of Chiapas, Tuxtla Gutierrez.
Human rights groups say many fall into the hands of organised criminal gangs who exploit and abuse them.
