PassBlue / August 18, 2026
Two weeks since news broke that an Israeli mole working inside the United Nations was leaking confidential information years ago to Israeli diplomats, the organization has released few facts about the allegations against Yahav Lichner. That means there are more questions than answers right now.
A Drop Site News investigation, published on Aug. 4, revealed that Lichner, a former Israeli diplomat, had from 2014 to 2015 repeatedly leaked top-secret information — some material marked by the UN Secretariat as “strictly confidential” — from his perch inside the UN Population Fund to Ron Prosor, the Israeli ambassador to the UN at the time, and other Israeli diplomats.
It is unclear if Lichner’s spying continued as he held other posts in the UN system over the last decade. The rules governing UN staff explicitly restrict them from passing information obtained through their positions to governments, including their own countries, or other outside parties.
Despite a follow-up article by PassBlue about the news, most of the circumstances around Lichner’s alleged spying remain a secret, as various UN spokespeople deflect questions about him. Lichner, 46, was working for UNICEF when it was reported that he had slipped UN documents and other private information of top UN officials to Israeli officials. That included details about Ban Ki-moon, the secretary-general at the time.
Lichner was put on administrative leave by UNICEF soon after Aug. 4, but it is unclear whether he is being paid. The agency referred to him in a statement to PassBlue only as an “employee” and did not name him.
When questioned about the Lichner allegations, the UN’s deputy spokesperson, Farhan Haq, also called Lichner an “employee” and directed all questions to UNICEF, which has revealed little, saying, “UNICEF is aware of serious allegations concerning an employee and is taking the appropriate action.”
Kurtis Cooper, media chief for the agency, also said: “UNICEF does not publicly discuss details of individual personnel, performance, or recruitment.”
Yet David Nyskohus, the chief of office for the Office of Internal Oversight Services, the UN’s internal investigative arm, told PassBlue that “OIOS is assessing whether any United Nations Secretariat personnel may have been involved in the alleged disclosure of confidential information that has been reported in the media. OIOS is working with UNFPA and UNICEF to facilitate this assessment.”
Employment snapshot
Lichner began his job in 2014 in external relations at the UN Population Fund (UNFPA), which focuses on women’s reproductive rights and health. He was hired through a competitive process, a spokesperson said for the agency.
He was seconded to UNICEF in 2018 and officially “separated” from UNFPA in 2022 while he was with UNICEF. By 2025, he was director of UNICEF’s Washington office, a plum job, when he was put on leave this month.
UNICEF had a presence in Washington before Lichner’s appointment, but the position of director appears to have been created in 2025. The agency’s initial role in the Capitol was relatively small and focused largely on managing relations with institutions like the World Bank. Lichner was the first person to hold the title of director for the D.C. post, although UNICEF has not clarified whether the post was publicly advertised or how Lichner was selected for it, including whether it was through a competitive procedure or an internal reassignment.
PassBlue could not find a public vacancy announcement for the post after searching UNICEF’s careers site and several websites that archive UN job postings. Earlier Washington-based UNICEF vacancies are publicly available, including positions advertised in 2023 and 2024, but PassBlue found no comparable listing for the director position Lichner assumed in 2025.
The Washington office acts as a leadership hub for UNICEF’s partnerships with “the Governments of the United States, Canada and Israel, as well as for UNICEF’s partnership with International Financial Institutions,” according to the agency.
Lichner’s LinkedIn and X accounts were recently deleted.
UNICEF is headed by Catherine Russell, an American who worked in the Biden administration. As executive director, Russell would likely have signed off on the promotion of Lichner to DC.
IDF tenure
Lichner was in the Israel Defense Forces from 2000 to 2006, when the compulsory conscription time for most males is two years and eight months. During those six years, the second intifada took place, one of the most violent uprisings by Palestinians against Israel and that lasted five years. PassBlue was unable to confirm his rank when he left the military.
It also remains unclear whether Lichner went through a competitive hiring process when he joined the team of Sigrid Kaag, a former Dutch politician and UNICEF official from 2005-2010. She was recommended by the Biden administration and appointed by UN Secretary-General António Guterres in December 2023 to take on a new role as senior humanitarian and reconstruction coordinator for Gaza, which was backed by the UN Security Council on Dec. 22, 2023. Lichner and others soon joined her new team.
The Council mandate was authorized to push Israel to allow more essential aid into Gaza amid severe restrictions imposed by the Israeli government in its war against Hamas. The mandate also stipulated that the coordinator was responsible for ensuring that the aid that got in was used for humanitarian purposes only.
The United Arab Emirates led the Council resolution (which was approved 13-0, with abstentions by Russia and the US). As to aid, the text specifically called for “urgent and extended humanitarian pauses and corridors throughout the Gaza Strip for a sufficient number of days to enable full, rapid, safe, and unhindered humanitarian access and to enable urgent rescue and recovery efforts.”
Additionally, it called for “the immediate and unconditional release of all hostages.” That call was eventually realized by early 2026.
Lichner’s role as an adviser for Kaag lasted approximately from January 2024 until September 2024, Kaag told PassBlue on Aug. 9, referring to it as a “secondment.” He worked from Jerusalem and New York City, while her overall office worked through “integrated teams” based in Amman, Jerusalem, Gaza and Cairo, in addition to New York City.
Kaag said “liaison was the mainstay” of Lichner’s role, likening it to other nationals who work, for example, in the Office of the UN Special Coordinator for the Middle East Peace Process (UNSCO), including “Israelis and Palestinians,” she added. The Gaza mandate ended in March 2025, but the mechanism continues to be handled by the UN Office for Project Services. Kaag is no longer affiliated with the UN.
Whether Lichner was selected based on a vacancy announcement for the post and review of applicants or whether there was no vacancy posted and Kaag personally requested him for the position is not clear.
The UN Office for the Coordination of Humanitarian Affairs, or OCHA, led the Gaza mission, but the spokesperson, Eri Kaneko, did not answer PassBlue’s email about Lichner’s hiring.
[Update, Aug. 19: Kaneko emailed PassBlue, after this story was published, with the following information: “OCHA was designated as a service provider and provided administrative support to the Office of the Senior Humanitarian and Reconstruction Coordinator (for example, issuing contracts). Decision-making and managerial responsibilities, such as selection and recruitment decisions, rested with the Senior Coordinator. OCHA was asked to provide administrative support to facilitate their operations, so on selections and recruitments, we’d refer you to the Senior Coordinator.]Kaag said the team was mostly comprised of UN staff “on secondments or (non) reimbursable loan, ranging from WHO, UNDP, WFP, OCHA and UNICEF.”
In a separate email, she said Lichner was hired on a P-5 contract through a non-reimbursable loan, given the nine-month initial time frame of the mission. At the UN, “P-5” refers to a “professional” level rank, usually requiring 10 years of experience and internationally recruited.
Lichner could have been deemed helpful with obtaining permits from the Israeli government to enter Gaza for the coordinator job, a UN official who worked in the region told PassBlue, given his connections as a former IDF member and having worked as a diplomat for the Israeli mission to the UN.
Money for the Gaza mission
Financial support to Kaag and her team appears to have been donated by the UAE and the Netherlands, among others. (Kaag is a former Dutch foreign trade/development minister, foreign minister and finance minister.)
A June 2024 UN update on the mechanism says it received a total of $11.7 million from the Netherlands ($5.4 million), the UAE ($5 million), and Australia ($1.3 million). The document identifies these amounts as funding for the “UN 2720 Mechanism.” By September 2024, the UN was reporting the donor list as: Netherlands, $7.2 million; UAE, $5 million; Australia, $1.3 million; Denmark, $2 million; Estonia, $30,000; New Zealand, $1.2 million; Minderoo Foundation, $4 million.
The Dutch Ministry of Foreign Affairs’ appraisal of its contribution to the UN coordinator mechanism says the program included “the placement of Sigrid Kaag” and that its budget was principally for staff and equipment. The same document says that the program required $61 million, and that the Dutch contribution was being made to enable the mechanism to be created.
It is difficult to assess how effective the mechanism proved to be amid accusations by wide-ranging experts that the Israeli government used food as a “weapon of war” throughout much of the conflict in Gaza. The ceasefire in the enclave from late January 2025 to March 2025 enabled aid flows to surge, but when the truce collapsed, Israel blocked food, fuel, medicine and other aid into Gaza.
Kaag told the Security Council at the time that the “entire population in Gaza is facing the risk of famine.”
Aid and other lifesaving supplies have been entering the enclave since the October 2025 ceasefire, albeit intermittently, as the agreement is regularly violated, mostly by the IDF.
Board of Peace
Kaag is currently an unpaid executive board member of the Trump-led Board of Peace, one of the few women in the organization, which includes Trump’s adviser and a son-in-law, Jared Kushner; and Steve Witkoff, another Trump adviser.
The board was endorsed by a UN Security Council resolution in 2025 to back the US-led Gaza peace plan, but it has yet to meet. Nickolay Mladenov, the board’s high representative, oversees governance of Gaza and the disarmament of Hamas, which has not proceeded.
Israeli Prime Minister Benjamin Netanyahu recently rejected the Gaza peace plan, but Kushner, who met with Netanyahu this week, said that if Hamas didn’t disarm over the next 60 to 90 days it’ll show “they’re not genuine about peace” and it will give Israel cover to “go and finish the job.”
The board states that at a minimum under the peace plan, quantities of aid getting into Gaza “will be consistent with what was included in the January 19, 2025, agreement regarding humanitarian aid, including rehabilitation of infrastructure (water, electricity, sewage), rehabilitation of hospitals and bakeries, and entry of necessary equipment to remove rubble and open roads.”
According to regular media briefings by the UN spokesperson, none of these goals has yet to be fully achieved. Fuel, for example, was recently restricted again by Israel into Gaza, leaving hospitals unable to function properly. Yet Resolution 2720 specifically “demands the provision of fuel to Gaza at levels that will meet requisite humanitarian needs.”
