Country: Iran (Islamic Republic of) Source: UN Office for the Coordination of Humanitarian Affairs Please refer to the attached file. This Humanitarian Update is produced by OCHA Regional Office for the Middle East and North Africa (ROMENA) on behalf of and in collaboration with UN agencies and humanitarian organisations. It covers the period from 4 April to 16 April 2026. Highlights A two-week temporary ceasefire was announced on 7 April, but the humanitarian consequences of earlier hostilities continue to affect populations nationwide. As of 7 April, at least 2,362 civilians were reported killed and more than 32,314 injured, with the highest casualties recorded in Tehran, Hormozgan and Isfahan. Extensive damage has been reported to housing and critical infrastructure alongside large-scale internal relocation, with approximately 3.2 million people temporarily relocated as of 15 April, some 60 per cent of them women and children. Vulnerable groups including women, children, persons with disabilities, refugees and people with chronic conditions are particularly at risk. Government‑led response efforts continue, supported by the Iranian Red Crescent Society (IRCS) and the international humanitarian community. However funding gaps, procurement challenges and market disruptions continued to hinder the scale and pace of the response. On 14 April, the Emergency Relief Coordinator allocated US$12 million from the UN Central Emergency Response Fund (CERF) to support life-saving, multi‑sectoral assistance targeting the most vulnerable people.

Most airstrikes were reported in Tehran, followed by the provinces of Hormozgan, Isfahan, Bushehr, West Azerbaijan, Khuzestan, Fars, Markazi, Sistan & Balouchestan, Alborz, Qom, Ilam, Hamedan among other provinces, resulting in civilian casualties, population displacement, and extensive damage to civilian housing and critical infrastructure. As of 7 April, the Ministry of Health and Medical Education (MoHME) reported at least 2,362 civilian deaths and more than 32,314 injuries nationwide. Casualties were reported across most affected provinces, with the highest numbers recorded in Tehran, Hormozgan, and Isfahan. Large‑scale damage to property was reported across the country. As of 10 April, the Iranian Red Crescent Society (IRCS) estimated that more than 125,600 civilian units had been damaged nationwide, including approximately 100,000 residential units and 23,500 commercial units. In Tehran, municipal authorities reported damage to around 40,000 residential units, with thousands of structures assessed as requiring moderate repairs, structural reinforcement, or full reconstruction, directly affecting housing stability and living conditions. On 15 April, IRCS further reported damage to 20 of its bases. Critical infrastructure sustained repeated damage, disrupting essential services and mobility. According to the Ministry of Energy, more than 1,000 electricity distribution and sub‑transmission points had sustained major damage nationwide as of 6 April, including over 470 points in Tehran Province, causing localized temporary power outages in areas such as Karaj and Fardis. Transportation infrastructure was also affected, with reports of damage to railway lines, highways and bridges, including the Tabriz–Zanjan highway, the Tehran–Karaj highway, and rail infrastructure in Alborz Province, as well as strikes affecting Khorramabad and Urmia airports, resulting in temporary disruptions to movement and access. As reported by IRCS on 15 April, 15 bridges and railway infrastructure sites, along with 5 fuel storage tanks were damaged due to airstrikes. Large‑scale population movements were reported during the period of reporting. As of 13 April, the Government of Iran reports that approximately 3.2 million people (around 800,000 households) had internally relocated since 28 February, of whom around 60 per cent are women and children. Cross‑border movements remained limited overall. As of 16 April, UNHCR (the UN Refugee Agency) reports that approximately 118,300 Iranian nationals crossed into neighbouring countries, nearly 113,000 to Türkiye and around 5,400 to Pakistan, while about 95,000 people were reported to have returned from Türkiye. The Agency considered that movements largely reflect routine, family‑related or precautionary travel rather than large‑scale cross‑border displacement, with 52 per cent of those crossing into Türkiye reported to be families. Furthermore, Iran continued to host around 1.65 million refugees and others in need of international protection. Natural hazards occurred during the reporting period. On 9 April, a 5.1‑magnitude earthquake struck near Astara in Gilan Province, with tremors felt across northern Iran. Separately, severe storms and flooding were reported on 7–8 April in Golestan Province, damaging the water infrastructure and causing water supply disruptions and reduced pressure in several cities and surrounding rural areas, according to local authorities.
