(Daily Caller News Foundation) – The U.S. officially blacklisted a former United Nations Relief and Works Agency (UNRWA) official over his alleged role in the October 7, 2023 terror attacks, investigators announced Monday.

The UNRWA, a UN agency intended to provide aid to Palestinian refugees, has been under investigation by the U.S. Agency for International Development Office of the Inspector General (USAID OIG) for allegations that employees were affiliated with or assisted Hamas during the attacks. According to the OIG’s investigative summary published Friday, Hafez Mousa Mohammed Mousa was allegedly “an operative of the Hamas East Jabaliya Battalion” while working as a UNRWA school principal.

In an X post on Monday, the USAID OIG wrote that Mousa’s case is “the first known debarment by the United States affiliated with a UN agency entrusted to implement humanitarian assistance programming.”

The summary added that Mousa “coordinated communications with other suspected Hamas members during the October 7 attacks.” Gov.il, the Israeli government’s official website, alleges that Mousa “made 5 phone calls and sent messages to more than 20 fellow operatives, ordering them to infiltrate Israel via the Erez crossing with cars and weapons” after telling his UNRWA area supervisor that “students are safe.” Over 1,200 men, women and children were murdered by Hamas in the attacks, including 46 Americans, according to the Department of State.

The Biden administration reportedly gave over $1,000,000,000 in taxpayer funds to UNRWA — 10% of which reportedly have links to Islamic terrorist organizations.

The OIG stated that its investigation has “referred for debarment two additional former UNRWA employees for their participation in the October 7 attacks,” as well as 14 former UNRWA employees affiliated with Hamas. According to the investigative summary, the office “has ongoing investigative work” focused on “preventing the recirculation of terrorist-affiliated actors across aid organizations operating in Gaza.”
