Tens of thousands of displaced Syrians are waiting to leave the remote Rukban refugee camp on the border with Jordan.
Conditions there are worsening, forcing nearly 2,000 people to leave using a corridor opened by the Russian military. They have gone back to their villages, which are under government control.
But many others in the camp are now seeking safe passage to the opposition-controlled north.
