"Intensifying hostilities across the Middle East have triggered significant population movement, while clashes along the border between Afghanistan and Pakistan have forced thousands of families to flee. Overall, more than 330,000 people have been forcibly displaced, mostly within their own countries," UNHCR spokesman Matthew Saltmarsh said in a March 6 press release.

About 100,000 left Tehran in first two days of conflict

The UN agency said that it is already supporting displaced populations and preparing to scale up its assistance "as needed."

Saltmarch stressed that: "We are also urgently calling for dialogue and de-escalation as violence intensifies," he added.

Iran is a long-term host to 1.65 million people forced to flee, mostly from Afghanistan. Around 100,000 people left Tehran in the first two days following the attacks, according to local estimates. More recent figures are not yet available, said Saltmarch.

He added that "there has so far been no major increase in cross-border movements from Iran linked to recent events."

Over 30,000 crossed into Syria since escalation started

In Lebanon, "over 84,000 people are now sheltering in nearly 400 collective sites, the government reports. And over 30,000 people -- mostly Syrians but also some Lebanese -- have crossed into Syria since the escalation began, according to authorities," the press release said.

The situation in Afghanistan and Pakistan with active conflict along the border remains tense, the UN said. Internal displacement is reported in both countries, including an estimated 115,000 people in Afghanistan and around 3,000 people in Pakistan.

"It is imperative that all civilians who need to move or cross borders to find safety are given safe passage," Saltmarsh stressed.
