Hundreds of migrants make their way to US border ahead of potential Trump win

Hundreds of migrants from a dozen countries have begun their journey through Mexico, hoping to reach the US border and make their way into the country.

Organized on social media, the caravan is assembling as the US presidential race gets underway, with Donald Trump vowing to crack down on illegal immigration should he win a second term. Trump has promised large-scale deportations if he is returned to the White House in November.
