Up to 3.2M Iranians Displaced Internally as Conflict Escalates – UNHCR

Preliminary UNHCR assessments reveal 600,000–1M Iranian households—up to 3.2 million people—temporarily displaced amid intensifying conflict. Most are fleeing Tehran and urban centers northward to rural safety, with numbers expected to rise. Vulnerable Afghan refugee families face acute risks amid insecurity and service disruptions. UNHCR is scaling operations with Iranian authorities for assessments, helplines, and aid, urging civilian protection, humanitarian access, and open borders per international law.
