Iran to Lebanon: Four million people displaced by US-Israeli war

EXPLAINERThree million Iranians and at least a million Lebanese have been forced from their homes because of US-Israeli attacks.Published On 26 Mar 2026The war launched by the United States and Israel has killed more than 1,500 people in Iran.This number is considered conservative, as actual calculations are yet to be released by the authorities.Recommended Stories list of 4 itemslist 1 of 4US-Israel war on Iran: What’s happening on day 27 of attacks?list 2 of 4Human cost of war: Four killed in Iran, Abu Dhabi as conflict expandslist 3 of 4Helium hitch: Why US-Israel war on Iran could cause MRI scan delayslist 4 of 4US seeks Hamas ‘political surrender’ in new Gaza planend of listBut the devastation from the war has also triggered mass displacement in the country: the United Nations refugee agency, UNHCR, estimates that 3.2 million people – more than 3 percent of the population – have already been displaced within Iran since US-Israeli strikes began on February 28.Twenty-seven days into the conflict, aid agencies and countries bordering Iran are bracing themselves for a potential refugee crisis as civilians begin to flee the violence.Cross-border flows have been limited and largely economic or short-term. In Afghanistan, most arrivals are Afghan returnees from Iran, citing insecurity or forced returns. Pakistan reports only authorised entries by citizens or traders, with no refugee inflows.Turkiye, Turkmenistan and Azerbaijan report stable borders, limited authorised crossings, and occasional evacuations of third-country nationals.Iraq has seen small-scale returns and 325 Iranian nationals crossing the border, citing the crisis. Within Iran, people have been forced from the ruins of their homes, and several hospitals, nuclear facilities, refineries and desalination plants have been hit.However, pressure on the ground in Iran is mounting as more than 85,176 civilian sites have been damaged since the war began, including 282 healthcare facilities, 600 schools and 64,583 homes. In Tehran alone, the city administration said to local media that nearly 14,000 residential units in the capital have been damaged and at least 6,000 people have been accommodated in municipal hotels.The growing risks of disruption to essential services are driving complex mobility patterns.More than one million displaced in LebanonBut Iran is not the only country where the rapidly expanding war has led to a displacement crisis.The Israeli army has expanded its forced displacement orders for residents of southern Lebanon – from the Litani River to north of the Zahrani River, about 40km (25 miles) north of the Israeli border.According to the Norwegian Refugee Council, Israel’s sweeping evacuation orders now cover more than 1,470sq km (568sq miles), or about 14 percent of the country’s territory.The map below shows more than 100 towns and villages across the country that are under forced evacuation orders from the Israeli military.Israel’s ground troops are also now increasingly expanding their de facto occupation of parts of southern Lebanon, with Israeli authorities claiming that they want to create what they describe as a “buffer zone”.Nearly one in five people in Lebanon – or 18 percent of the population – have been displaced over the past two weeks.According to the International Organization for Migration, the total number of registered displaced people has reached 1,049,328, and the number of displaced people residing in collective shelters is 132,742.The pace of displacement has outstripped the country’s shelter capacity. Many families have been unable to secure accommodation and are spending nights in streets, vehicles or public spaces as collective shelters fill up. For many of them, this is not the first time.More than 250,000 people have left Lebanon over the past two weeks, a 40 percent increase compared with the last two weeks of February.Much of the outward movement has been towards neighbouring Syria. As of March 17, more than 125,000 people had crossed the border. Nearly half are children. Most are Syrian nationals, with about 7,000 Lebanese among those crossing.Southern Lebanon’s bridges attackedIsrael has struck several bridges in southern Lebanon, connecting the country through the Litani River.Israeli forces have attacked: Qasmiyeh Bridge. Coastal Highway Bridge. al-Qantara Bridge. Khardali Bridge. al-Dalafa Bridge. Zaraiya-Tirseflay Bridge. Footage and photos of the locations, verified by Al Jazeera, show each bridge specifically bombed, making them impossible to use. These were key crossings linking Lebanon’s south.Israeli Defence Minister Israel Katz had last week ordered the military to destroy all crossings over the Litani River and homes close to the border between the two countries.The areas in Lebanon near the Israeli border to the Litani River are the same locations where at least a million people have been pushed out.Lebanese President Joseph Aoun has said the attacks on the bridges are “an attempt to sever the geographical connection between the southern Litani region and the rest of Lebanese territory”.He said they fell “within suspicious schemes to establish a buffer zone along the Israeli border, solidify the reality of the occupation and seek Israeli expansion within Lebanese territory”.
