Mexican authorities said they found and detained more than 500 illegal immigrants from Central America and Asia who were crammed inside two tractor-trailers heading toward the United States on Tuesday.
X-ray equipment detected the immigrants at checkpoints in the southern state of Chiapas, the state attorney general's office said. The drivers of both trucks sped away after authorities ordered them to stop, but police apprehended them nearby.
Inside the tractor-trailers, they found 513 people from El Salvador, Ecuador, China, Japan, Guatemala, India, Nepal, Honduras and the Dominican Republic.
