Four million people displaced by US-Israeli war

The 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.

But 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.

The growing risks of disruption to essential services are driving complex mobility patterns.

More than one million displaced in Lebanon
But 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 attacked
Israel has struck several bridges in southern Lebanon, connecting the country through the Litani River.

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.

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”.
