In a no-man's land on Syria's border with Iraq and Jordan, thousands are stranded in an isolated camp, unable to return home after fleeing the government and militants years ago. When police defector Khaled arrived at Rukban, he had hoped to be back home within weeks -- but eight years on, he is still stuck in the remote desert camp, sealed off from the rest of the country. Damascus rarely lets aid in and neighbouring countries have closed their borders to the area, which is protected from Syrian forces by a nearby US-led coalition base's de-confliction zone.
