GENEVA — The Board of Peace will ask the United Nations Security Council to press Hamas to disarm as a condition for advancing the Gaza ceasefire plan, according to a report expected to be discussed Thursday when the council meets on the situation in the Middle East. The board is an international body set up by U.S. President Donald Trump and tasked with overseeing the ceasefire between Hamas and Israel.

"At this stage, the principal obstacle to full implementation of the ceasefire remains Hamas' refusal to accept verified decommissioning, relinquish coercive control, and permit a genuine civilian transition in Gaza," the report said. A diplomat familiar with the document confirmed its authenticity on condition of anonymity because it has not been made public.

The report calls on the Security Council to reiterate that decommissioning weapons in Gaza is critical for reconstruction to begin, for a time-bound Israeli forces withdrawal, and for a credible pathway to Palestinian self-determination and statehood. "Reconstruction cannot commence where weapons have not been laid down," it states, adding that "The critical variable — the single factor that unlocks every other element of the plan — is the conclusion of an agreement on the Roadmap for the full implementation of the plan that includes full decommissioning by Hamas and all armed groups in Gaza."

Trump's 20-point ceasefire plan calls on Hamas to surrender its weapons and destroy its network of tunnels. It also envisions Israeli forces withdrawing from Gaza, the arrival of a new technocratic Palestinian government, the deployment of an international security force, and the rebuilding of the enclave after more than two years of war. The Security Council endorsed the Board of Peace in a resolution in November.

Nickolay Mladenov, the head of the Board of Peace and a former U.N. Mideast envoy, said the truce had stalled since taking effect in October and that the deadlock over disarming Hamas had paralyzed progress. He said his office is addressing violations by both sides on a daily basis. Mladenov said that Hamas' obligation to give up its arsenal is "not negotiable" and that progress on all other issues was being held up.

The report noted near-daily ceasefire violations, "some of which are serious, and their human consequences — civilians killed, families living in fear, and continued impediments to humanitarian access — cannot be minimized." Israel's military has expanded its control of Gaza since the truce took effect and now controls about 60% of the territory, more than it was granted under the ceasefire agreement.

Hamas rejected the report, saying it contains "a number of fallacies that absolve the occupying government of its responsibilities for the daily violations of the ceasefire agreement in Gaza." The group said the report ignored Israel's "failure to uphold the majority of its commitments" in the ceasefire deal, including restrictions on crossings into Palestinian territory and preventing the entry of material and equipment needed to repair basic infrastructure and shelter for the largely displaced population. Hamas has also sought to link any demilitarization to Israeli troop pullbacks.
