One Honduran youth was shot to death and another migrant was wounded when assailants attacked Central American migrants riding a freight train in the central Mexico state of Puebla.

The shootings in Puebla may indicate gangs are following Central American migrants in their changing routes through Mexico.

Migrants had frequently rode trains and been attacked by gangs in the southern and Gulf coast states of Chiapas, Oaxaca, Tabasco and Veracruz. But raids by immigration agents on the trains in Chiapas and Oaxaca have led many migrants to catch freight trains farther north. The thieves and extortionists have apparently followed them.

The Puebla state prosecutor's office said Tuesday the attackers apparently boarded the train around Tierra Blanca, Veracruz, before the line turns inland and heads toward the center of Mexico.
