The ambassador said the intent of his letter was to share some "additional information" on who they had identified, which included a "document containing 100 names and IDs of terrorist operatives who are currently employed by the UNRWA-Gaza."

"This list includes their military IDs as well," said Weissbrod, according to the letter.

"Israel expects from you and your organization to immediately terminate the employment of any member of Hamas or PIJ...their work in UNRWA poses a security risk for Israel, and represents a breach of the principle of neutrality as was mentioned in Ms. Colonna's report," he said, adding that "This list will also be provided to major UNRWA donors."

The UNRWA has previously acknowledged the authenticity of the information, and the Israeli government has released numerous photographs, videos, and documents that demonstrate Hamas militants' involvement within the organization. Phillipe Lazzarini, the Commissioner-General of UNRWA, declared in January that he had terminated UNRWA personnel who were implicated in the attack on Oct. 7.
