This week, we bring you the story of two brothers, who grew up officially stateless in a Palestinian refugee camp in Syria, before they escaped for a new life in France back in 2013.

And we finish with one of the world's biggest engineering projects, as car-crazed Qatar braces itself for a metro system. But will anyone actually use it?
