Iran has deported more than 300,000 Afghan migrants since early June, with a total of over 900,000 deported in 2025 so far, according to the International Organization for Migration. The UN reported Iran set a July 6 deadline for Afghans to leave. Many returned through the Islam Qala border in Herat. Returnees report increased pressure and harsh treatment in Iran, especially after an attack in Tehran. Afghan authorities are urging Iran to treat migrants humanely, while human rights groups warn mass deportations risk destabilizing Afghanistan.
