 That report was from Rachelle Krieger. You can hear more on that story on BBC Trending. Search for the documentary wherever you get your podcasts. And don't forget, if you want to listen to this programme but miss the live broadcast, there's a podcast available, updated shortly after we come off air, twice a day. You can subscribe to the feed as well if you want to get it on a regular basis. I'm Paul Henley with NewsHour Live from the BBC World Service.
