ARI SHAPIRO, HOST:
I'm Ari Shapiro in Poland near the border with Ukraine. The refugee crisis here has entered a new phase. The flow of people has changed direction. Every day for about the last week, more people have been entering Ukraine than leaving, according to Poland's border guard.
David Miliband is head of the International Rescue Committee, and he joins us to talk about the Ukrainian refugee crisis and the global response. It's good to have you here again.
