AMANPOUR: And finally tonight, we imagine a distressed anniversary. This Friday, the Zaatari refugee camp will mark five years since it was set up as a temporary base for Syrians fleeing their brutal war. Located just inside the border with Jordan, it's now the largest Syrian refugee camp in the world. And half a million people have passed through. At any one time it's home to tens of thousands. When I visited the camp earlier this year, I found a place of pain but also some hope.</s>AMANPOUR: This is Zaatari, a sprawling refugee city of 80,000 that has morphed from tents and top pollen to fixed abodes with electricity. Most of these camps inhabitants fled when the war erupted in Daraa.</s>UNIDENTIFIED FEMALE (through translator): At first we were moving from place to place. For fear of the bombings. Nowhere was safe for us. And the children suffered. They were in constant fear. And whenever they heard a noise, they hid. They started to have some sort of posttraumatic stress.</s>AMANPOUR: Here, some 1,000 refugees a day come dressed in their best hoping to find their own gateway to somewhere. Mindful of the Trump administration's efforts to ban Syrian refugees. The UNHCR Paul Stromberg tells me vetting here is about as extreme as it gets. Every day Syrians try to voluntarily head back across the border. If only Bashar al-Assad and his barrel bombs would let them.</s>AMANPOUR: And we are still waiting for some final resolution to that war. And that's it for our program tonight. Remember, you can always listen to our podcast, see us online at Amanpour.com and follow me on Facebook and Twitter. Thanks for watching and good-bye from London.
