Thousands of people from Honduras have left their homes in the last few days, hoping to reach the United States.

Some have reached the Guatemala town of Tecun Uman, which is just on the border with Mexico.

But many are unaware that the US has already put in place plans to send them back to Guatemala in planes should they manage to head north.
