Where did the crisis in the Congo come from?

There are 6 million people displaced in the Eastern Congo. It's a humanitarian catastrophe, two million of those, roughly speaking, are displaced by the M23 conflict. They don't know where they're going to eat, they're going to drink, where to get healthcare. You don't know what tomorrow is going to bring. It's extremely militarised. There are people with guns everywhere. So you're talking about a population that's now living, it's in its 29th year of conflict. It's a generation of Congolese that's known nothing except that sort of precarious existence.
