A federal oversight body in the United States is broadening its inquiry into suspected connections between employees of a United Nations aid organization and Hamas, including potential involvement in the October 7 massacre.

The Office of the Inspector General for the now-closed U.S. Agency for International Development is reviewing more than 100 staff members from the United Nations Relief and Works Agency amid concerns that some may have ties to Hamas or may have taken part in the October 7 attack, according to individuals familiar with the investigation.

According to a report by The New York Post, investigators have already flagged at least 14 UNRWA employees for alleged links to Hamas. Two others have been recommended for debarment, a step that would prevent them from receiving U.S. funds, while one former staffer has already been permanently barred from federal support.

Officials say the probe remains active, with the number of individuals being examined continuing to rise. The deputy inspector general of USAID is expected to brief members of Congress on the findings, emphasizing the continued importance of the oversight office even after the agency’s shutdown and amid discussions about transferring its functions to the State Department.
