NEW YORK CITY: Top UN officials on Wednesday warned the Security Council that there is a risk the fragile situation in Yemen could rapidly deteriorate, as they called for both intensified diplomatic efforts and increased humanitarian funding to stave off further instability and ease human suffering.

With Yemen’s economy in free fall and millions in need, they said time is running out to turn “hope into progress.”

The UN’s special envoy for Yemen, Hans Grundberg, and deputy emergency relief coordinator, Joyce Msuya, also highlighted the ongoing detention of UN workers and employees of nongovernmental organizations by the Houthis, a year after dozens were arbitrarily arrested.

“Their continued imprisonment is shameful,” said Grundberg. “I call again, in the strongest terms, for their immediate and unconditional release.”

Msuya echoed this condemnation, saying: “Twenty-three UN staff remain detained. I join the special envoy and the (UN) secretary-general in calling for their immediate release.”

The detentions, some dating back as far as 2021, have cast a long shadow over ongoing diplomatic efforts to reach a comprehensive peace agreement in Yemen, where multiple front lines remain active in the civil war and recent regional escalations have complicated a fragile status quo.

The Houthis, the official name for whom is Ansar Allah, have launched missile attacks on Israel in recent weeks, including one that targeted Ben Gurion Airport. Israel in turn struck Houthi-controlled infrastructure, including the destruction of a civilian aircraft at Sanaa International Airport. Grundberg warned that such escalations directly harm ordinary citizens.

“Yemenis living in Ansar Allah-controlled areas are unable to fly commercially from Sanaa Airport to seek medical treatment abroad, to travel for Hajj or visit their families,” he said.

He described the reopening of the airport in May 2022 as a key peace dividend of a now-lapsed truce agreement that year.

Meanwhile, the humanitarian crisis in Yemen continues to deepen. Msuya described a deteriorating health and food-security situation affecting millions.

“Over 17 million people, or nearly half of Yemen’s population, are acutely hungry,” she told council members.

“Malnutrition affects 1.3 million pregnant and breastfeeding women and 2.3 million children under 5. Without sustained humanitarian support, an estimated 6 million more people could end up in emergency levels of food insecurity.”

Despite the challenges, Msuya noted some progress has been made, including the reopening of a key route between Aden and Sanaa via Al-Dhalea, which had been closed for nearly seven years.

“This development … shows that Yemen is not on a fixed, downhill trajectory,” she said. “With trust and the right tools, there remains hope.”

Grundberg also pointed to this development as a positive sign.

“I commend, again, the local facilitators across the front lines who worked to make this happen,” he said. “Yemen’s economy is in dire need of positive and trust-building steps such as these.”

However, the path forward in the country remains uncertain. Grundberg reported increased tensions around Marib, and troop movements in several governorates, warning that “conditions can change rapidly and unpredictably.”

Both officials reiterated that a long-term solution will require a political settlement and increased support from regional authorities.

Grundberg said he has held talks with the Yemeni government, the Houthis, and regional authorities including Saudi Arabia, Iran and Oman, and noted that there is a shared view that only negotiation can end the conflict.

He urged council members to “use your powerful voices, your diplomatic channels and your influence, to exert maximum pressure” on the Houthis both in the pursuit of peace and to secure the release of detainees.

Msuya concluded her remarks with three direct appeals: “Take the lead of the Senior Officials Meeting in May and follow up with scaled-up, flexible funding; take real action to see that UN and other detained colleagues are released…; (and) maintain your unified support for efforts toward lasting peace.”
