175 migrants found in truck near US southern border

STORY: Immigration agents heard yells and banging coming from inside the vehicle when it was stopped at a checkpoint in Chiapas, INM said in a statement.

Although the driver refused to open the truck's back door, the faces of migrants could be seen through vents in the compartment, INM said.

Images released by the institute showed people standing closely together inside the truck before descending one by one with the help of INM agents.
