Angelina Jolie, a UNHCR Goodwill Ambassador, flew to Syria on Monday and visited Iraq on Tuesday, meeting with refugees displaced by war.

"I have come to Syria and Iraq to help draw attention to this humanitarian crisis and to urge governments to increase their support for UNHCR and its partners," Jolie said. "My sole purpose in both countries is to highlight the plight of those uprooted by the war in Iraq."

The UN refugee agency estimates more than 4.2 million Iraqis have left their homes. Jolie said, "It is absolutely essential that the ongoing debate about Iraq's future includes plans for addressing the enormous humanitarian consequences these people face."

Jolie also met privately with U.S. troops while in Iraq.
