Relatives and victims of attacks by Hamas and Hezbollah have filed a lawsuit against the United Nations agency that aids Palestinians, accusing it of supporting these armed groups and fueling terrorism. The case, brought by American citizens and their families, seeks monetary damages and alleges that the agency has violated antiterrorism laws by providing direct and indirect support to the groups. The lawsuit also claims that the agency has allowed militants to infiltrate its institutions and facilitate military activities, echoing longstanding accusations by Israeli officials. The agency and its supporters deny these allegations, asserting it works for stability in the region, while critics argue it fosters hostility and enables violence.
