Refugees at the Zaatari refugee camp in Jordan try to squeeze on one of the buses heading back to Syria. Syrian refugees have been coming to Jordan for two years, but some are now starting to head home.
In the Jordanian desert, the chaos begins at sundown, when the wind whips up the desert sand and the buses arrive. For the past two years, Syrian refugees have been streaming into Jordan, and they now number an estimated half million.
But for the past month, more refugees have returned to Syria than entered Jordan, and hundreds are leaving daily from Zaatari, the U.N.'s largest refugee camp in Jordan.
"Four buses are going every day," says Kilian Kleinschmidt, who runs Zaatari. "Depending on how many people manage to storm the buses, it's probably 300 to 400 people."
We've been following the story of the collapse in Bangladesh of a building that housed several factories where clothes were made for Western retailers. More than 1,000 people died in that disaster in April, and the incident shed light on working conditions in Bangladesh, the world's No. 2 exporter of clothing.
