President Donald Trump has again threatened to close part of the border with Mexico, if the country doesn't do more to stop undocumented migrants from entering the US.
He also renewed his threat to send more troops to the border.
This comes after Mexican police detained hundreds of Central American migrants in the southern Mexican state of Chiapas.
