There are over two million: one million have crossed into Syria and over one million have crossed into Jordan. Those numbers were increasing daily. But now that the Syrians and the Jordanians have closed the border and there are six-month certificates that have to be renewed, they're pushing people back. There is an enormous state of flux. There are at least two million people who would be, by UN definition, considered refugees, which means persecuted, with reasonable fear of persecution, outside their country of origin.
There are probably another two million or two and a half million who've been displaced within Iraq, many of whom have gone to the more stable region in the north. People have gone to Egypt and places like that. The situation is serious and it's not getting better. It is getting worse, if anything.
