The movement said in a statement that it "condemns the American position supporting the Zionist occupation's decision to ban the work of UNRWA."
She added, "We consider this position an extension of a history of blatant American bias toward the occupation and its actions that conflict with international law and humanitarian conventions."
She stressed that "the American intervention before the International Court of Justice (Wednesday) was consistent with the Zionist position seeking to undermine the role of UNRWA and tighten the chain of genocide around our Palestinian people, in light of the brutal starvation crime being perpetrated against innocent civilians in the Gaza Strip."
She stressed that "the accusations leveled by the occupation against UNRWA are blatant lies, concealing criminal efforts to eliminate the agency and end its relief role for our people, particularly the Palestinian refugee issue."
In its statement, Hamas called on the international community and the United Nations to "stand firmly against these dangerous policies, work to ensure the continued operation of UNRWA, and support it financially and politically so it can perform its duties in accordance with the UN mandate."
Earlier on Wednesday, US envoy Josh Simmons, in his address to the International Court of Justice, claimed there were "concerns" about UNRWA's neutrality, arguing that "international law does not compel an occupying power to deliver humanitarian aid."
He defended his country's support for Israel's blocking of humanitarian aid to the Gaza Strip, saying, "International law includes provisions requiring neutrality in the flow of aid to those who deserve it, which is not the case in the Gaza Strip," he said.
On Monday, the International Court of Justice, the United Nations' principal judicial organ, began hearings that will continue until next Friday. 40 countries, excluding Israel, and four international and regional organizations are participating.
The Court is hearing the arguments of these countries and organizations in preparation for issuing an advisory opinion requested by the United Nations General Assembly on Israel's obligations regarding the presence of the activities of the United Nations and other organizations in the occupied Palestinian territory.
This request came after the Israeli Parliament (Knesset) approved a law on October 28, 2024, banning UNRWA's activities, despite the Palestinians' dire need for its services under the genocide being perpetrated against them by Tel Aviv.
