The US President Donald Trump has sent 1,500 troops to the US-Mexico border to install barriers as part of his immigration crackdown.
Up to 10,000 troops could be ordered there, while a military source says they won't be involved in "law enforcement”.
Donald Trump has been highly critical of the Biden administration's approach to immigration, pledging to address "record" illegal border crossings and casting current migration as an "invasion".
Crossings did reach record levels under President Biden, but numbers began dropping significantly even before Trump won the election.
