Some Iranians and Afghans have taken to social media to condemn authorities in the Iranian city of Shiraz for putting arrested, blindfolded Afghan refugees on display.

The criticism came after Iranian media, including the semi-official ISNA news agency, published a series of photographs of Afghans -- who had been detained on suspicion of illegally entering the country -- sitting behind barricade fences wearing white blindfolds.

A sign on one of the fences said: “Arrest of foreign nationals.”
