2 years since Taliban retook Afghanistan, its secluded supreme leader rules from the shadows

On the border with Pakistan, thousands of Afghans are waiting in line to get their passports stamped so they can leave Afghanistan behind and never return. 

On this hot and humid day, as they cram between two fences like livestock, the sight of desperate travelers passing out is all too common, with waiting times averaging from three hours to a whole day during the busiest periods. 

The only relief from the heat is the bottled water sold by children as young as five who run up and down the fence shouting prices at thirsty travelers.
