INSIDE THE AMERICAS
At least nine Mexican migrants have died in a freight train crash. The train, known as "the beast", carries thousands of people every year looking for a fresh start across the border in the US. Also on the show, it is now 50 years since Martin Luther King's famous "I have a dream" speech. Just how far has the US come in making that dream a reality? Finally, we meet a French woman who is living her American Dream riding across the country on motorbike.
