Afghans leave Iran in thousands as economy worsens

Thousands of Afghan workers and refugees are leaving Iran each week because of the dire economic situation caused by United States sanctions.

They say rising prices and the falling value of the Iranian rial makes it impossible to survive.

For some Afghans, the desperation for work now outweighs the dangers they once ran from.
