An Afghan refugee comforts his companion while waiting for transport across the eastern border of Iran, on 27 July. UNHCR reports that Iran has almost one million registered refugees, the vast majority from Afghanistan. In addition, more than 1.5 million undocumented Afghans are estimated to be present in the country. Many people fleeing violence, insecurity and poverty in Afghanistan find no alternative but to use illegal traffickers, along routes where they are exposed to robbery, kidnapping and death. Their aim is to pass through Iran and Turkey or Greece to seek a better life elsewhere, but trafficked refugees are highly vulnerable to forced labor, debt bondage, forced marriage, or work in the sex trade.
