Iran's Internal Displacement Crisis Reaches 3.2 Million as Middle East Conflict Intensifies
Geneva, 13 March 2026
The UN refugee agency reports that up to one million Iranian families—approximately 3.2 million people—have been forced to flee their homes within Iran due to ongoing warfare. Most are escaping from Tehran and major urban centres to northern regions and rural areas seeking safety. This massive internal displacement represents one of the largest humanitarian crises in the region, with numbers expected to rise as hostilities continue. The displacement affects not only Iranian citizens but also vulnerable refugee families, particularly Afghans, already living precariously within Iran’s borders.
Displacement Crisis Unfolds as Conflict Enters Third Week
This crisis builds upon the European migration officials’ urgent preparations that began following the coordinated US-Israeli airstrikes on Iran starting 26 February 2026, as previously reported in our analysis of the potential refugee crisis. The UNHCR’s latest figures, released on 13 March 2026, confirm that between 600,000 and one million Iranian households have been temporarily displaced within Iran’s borders [1][2]. The displacement predominantly affects Tehran and other major urban centres, with families fleeing northward to rural areas in search of safety [1][2]. These numbers are expected to continue rising as hostilities persist, representing what the UNHCR describes as ‘a worrying escalation of humanitarian needs’ [4].
Afghan Refugees Face Double Vulnerability
The humanitarian crisis extends beyond Iranian citizens to affect the most vulnerable populations already within the country’s borders. Afghan refugee families, who constitute a significant portion of Iran’s foreign population, face particular risks due to their precarious legal status and limited support networks [1][2]. These families are abandoning affected areas amid increasing insecurity and restricted access to essential services [1][2]. The situation is particularly acute given that Iran expelled over one million Afghans to their home country last year [3], highlighting the cyclical nature of displacement in the region.
Regional Displacement Multiplies Humanitarian Challenges
The Iranian displacement crisis forms part of a broader regional catastrophe affecting multiple countries simultaneously. In Lebanon, Israeli attacks since 2 March 2026 have resulted in at least 687 deaths, including 98 children, with approximately 816,000 people displaced within a single week [3][4]. An additional 92,000 people have fled from Lebanon to Syria [3], whilst the Lebanese Ministry of Public Health reports nearly 500 deaths due to bombardments [5]. The displacement patterns mirror tactics previously employed in Gaza, with Israel issuing evacuation orders for large areas in southern Lebanon and Beirut’s southern suburbs [5].
Economic and Operational Impact on Aid Response
The UNHCR is adapting its long-established presence in Iran—including operational reception centres, helplines, and ongoing support services—to address the escalating needs [1][2]. The agency is working with national authorities and partners to assess emerging requirements and strengthen readiness as population movements increase [1][2]. The conflict’s economic toll has reached over $17.5 billion according to the Iran War Cost Tracker as of 11 March 2026, averaging $1 billion per day [4]. Oil markets have responded dramatically, with Brent crude briefly surpassing $100 per barrel due to Iranian attacks in the Persian Gulf, prompting 32 countries to release 400 million barrels from strategic reserves [4].
