53 killed in Mexico

At least 53 migrants crammed into a truck traveling at high speed were killed Thursday in Mexico after the vehicle overturned in the southern state of Chiapas, a major transit point for those trying to reach the United States.

Thousands of people attempt the long and hugely dangerous journey, often seeking a life free of violence and poverty in their home nations in South America.

It is unclear how many people were traveling in the truck but at least 58 were injured, three seriously, according to a preliminary report from the prosecutor's office in Chiapas, bordering Guatemala.
