This week’s Unreported World comes from one of the most hostile places on earth: the Sonora desert in Northern Mexico. Hot, waterless and full of rattlesnakes, it’s crossed every day by thousands of migrants desperate to reach the USA, many of whom die a lonely death trying to fulfil their dream of a better life.

Reporter Aidan Hartley and producer Julie Noon come across a monument to the more than 2,950 people, including children, who have died in this part of the desert. They are just some of the estimated million people who try to cross the border every year.
