The United Nations' investigation into 12 United Nations Relief and Works Agency (UNRWA) workers suspected of participating in the Hamas massacre that claimed the lives of 1,200 people, including over 30 Americans, has come under scrutiny. The inquiry, launched by the UN's Office of Internal Oversight Services, is facing accusations of incompetence, anti-Israel bias, and corruption.

Last month, the UNRWA confirmed the authenticity of an Israeli dossier that identified 12 of its employees as having been involved in the Hamas terror invasion. In response, the agency swiftly terminated the individuals implicated in the attack.

However, concerns have been raised about the UN's ability to conduct a fair and impartial investigation. Peter Gallo, a former investigator at the Office of Internal Oversight Services, described the agency as "as independent as my left kidney." Gallo shared a case where the agency allegedly dismissed a large-scale medical fraud linked to Hezbollah, a Hamas ally.

Gallo highlighted one instance in Naqoura, Lebanon, where the UNRWA's medical insurance claims were flagged as suspicious due to the absence of diagnostic tests. The investigation failed to bring in a medical expert and subsequently closed the case, relying on testimonies from potentially biased sources.

Gallo also raised questions about the alleged whitewashing of another terrorism-related case by the UN. In 2015, an American lawyer involved in UN investigations claimed that the organization's internal investigation services lacked independence and were unwilling to scrutinize senior-ranking officials.

The UN's investigation into UNRWA workers' alleged involvement in the Hamas massacre is set to be conducted by former French Foreign Minister Catherine Colonna and three independent Nordic research institutes. The final report will be made public upon completion.

Critics, however, have cast doubt on the integrity of the UN investigations. Anne Bayefsky, director of the Touro Institute on Human Rights and the Holocaust, voiced skepticism over the notion of an "independent" review, as it would involve the UN investigating itself and consulting with the UNRWA commissioner-general, who is implicated in corruption allegations.

Despite the criticisms, the United States government has expressed support for the UN's investigation, stating that "there must be complete accountability" for those involved in the October 7 attacks. The US has reached out to the government of Israel to gather more information on the allegations.

The UNRWA, UNRWA spokesperson Juliette Touma, and the UN's New York and Washington D.C. offices have not yet responded to queries regarding the investigation.

As the probe continues, many await the final report to determine the veracity and transparency of the investigation into the alleged involvement of UNRWA employees in the Hamas massacre.
