The migrant caravans to the US border have generated no shortage of debate among politicians and the public. Take a look at Mexican photojournalist Guillermo Arias' award-winning depiction of their perilous journey.
Mexican photojournalist Guillermo Arias has won the prestigious Visa d'Or for News photojournalism prize for his depiction of the Central American migrant caravans.
The photographer with the Agence France-Presse news agency was recognized on Saturday for his story entitled "The Caravan" at photojournalism's biggest annual festival, besting competition from The New York Times, Reuters news agency and The Washington Post.
Throughout 2018 and 2019, migrant caravans with thousands of people made the way northward from Central America. Most were heading to the US border in a bid to escape poverty and violence in their home countries.
In response, the US sent troops to secure the border. Washington also set up controversial camps to detain those who crossed the border illegally, instigating a draconian policy where children were separated and detained away from their families.
