The United Nations refugee agency and the World Health Organization issued a joint emergency appeal Monday for $1.4 billion in supplemental funding, warning that host-country aid systems in Lebanon and Jordan were approaching the point of collapse under a fresh wave of displacement triggered by the widening Iran-Israel war.

In a briefing delivered simultaneously in Geneva and Amman, UNHCR deputy high commissioner Kelly Clements said the agency had registered more than 218,000 newly displaced people across the eastern Mediterranean since the start of March, with arrivals in Jordan and Lebanon accelerating sharply over the past ten days as Israeli air operations expanded north of the Litani River and as cross-border shelling intensified along the Iraqi-Jordanian frontier.

“We are not at the edge anymore. We are past it,” Clements said. “Clinics in the Bekaa are turning away walking wounded. Schools in Mafraq are sheltering three families per classroom. This is the second-largest displacement event the region has absorbed in a decade, and the funding picture is the worst we have seen since 2019.”

The appeal landed one day after a separate UN briefing in Baghdad estimated that some 47,000 Iraqi civilians had fled Anbar and the outskirts of Erbil during the prior week, most heading east toward Sulaymaniyah or south toward Najaf rather than across borders. Monday’s announcement reframed the crisis as a regional one, drawing attention to flows that have so far received less coverage: Lebanese Shia families moving north from the south, Syrians long resident in Lebanon attempting a second displacement into Jordan, and a smaller but growing stream of Iranian dual nationals trying to exit overland through Turkey.

WHO regional director Dr. Hanan Balkhy told reporters that 14 hospitals in southern Lebanon were operating above 130 percent of rated capacity and that fuel reserves for generators at six of those facilities would be exhausted within nine days at current consumption rates. She said two pediatric wards in Nabatieh and Tyre had been forced to consolidate, and that a UNICEF-supplied cold chain for routine vaccinations had broken down in three southern districts after grid power failed during last Wednesday’s strikes.

“The medical system is not collapsing because of a single shock,” Balkhy said. “It is collapsing because every prop underneath it — fuel, staff, supply runs, the willingness of nurses to keep coming to work — is failing at the same time.”

Jordanian officials, who have been publicly cautious about discussing intake numbers, confirmed Monday that the kingdom had opened two transit reception sites near Ruwaished and a third outside Azraq, expanding capacity by roughly 18,000 beds. Interior Ministry spokesman Mazen al-Faraya said Jordan was coordinating closely with UN agencies but that the country, already host to more than 1.3 million registered Syrian refugees, could not absorb a sustained influx without substantial international support.

“Jordan has done its share, and more than its share, for fifteen years,” al-Faraya said in a statement carried by the state news agency Petra. “What we are asking for now is not charity. It is burden-sharing, and it is overdue.”

In Beirut, caretaker Prime Minister Najib Mikati met with envoys from the European Union, Saudi Arabia and Qatar to discuss an accelerated disbursement of previously pledged aid, much of which has been held up by Lebanese banking-sector restrictions and donor concerns about onward transfers. A senior European diplomat, speaking on condition of anonymity because the talks were ongoing, said EU member states were “actively considering” releasing roughly 340 million euros that had been earmarked for Lebanon in late 2025 but never moved, and that a decision could come within the week.

The appeal also drew attention to a quieter humanitarian thread: the impact of tightened sanctions enforcement on civilian goods inside Iran. Layla Hassan, a Beirut-based regional analyst with the Levant Policy Forum, said that while the headline humanitarian story remained the Iraqi and Lebanese displacement, the medium-term picture inside Iran itself was worsening rapidly.

“You have a population of 88 million people whose access to imported insulin, dialysis consumables and pediatric oncology drugs is being cut off in slow motion,” Hassan said. “The war is doing the visible damage. The sanctions architecture is doing the invisible damage. Both will show up in mortality data, just on different timelines.”

The Iranian Red Crescent on Sunday reported that imports of 23 categories of medical supplies, including specialty cardiac medications and infant formula, had dropped between 40 and 70 percent over the prior six weeks. Iranian state media attributed the shortfall to expanded U.S. Treasury designations on shipping intermediaries; a Treasury spokesperson, asked about the figures, said sanctions exemptions for humanitarian goods remained “fully in force” and pointed to authorized humanitarian channels established under existing general licenses.

Aid groups operating in the region described conditions on the ground as compounding faster than the funding response. Mercy Corps country director for Lebanon, James Reilly, said the organization had begun rationing winter-supplies kits in three governorates and had paused new caseload intake at four of its protection centers. The International Rescue Committee said its case-management ratios in Jordan had risen to one social worker per 340 households, a level it described as “incompatible with meaningful case work.”

A spokesperson for the UN Office for the Coordination of Humanitarian Affairs said donor pledges against Monday’s $1.4 billion appeal would be tracked publicly on a daily basis and that a follow-up pledging conference, jointly hosted by Switzerland and Saudi Arabia, was being scheduled in Geneva for the second week of April. Officials said additional appeals covering Iraq and Yemen would be issued separately later in the week.
