The administration of U.S. President Donald Trump is reportedly concerned that Israeli Prime Minister Benjamin Netanyahu could undermine the peace plan for Gaza proposed by the American leader, according to The New York Times.

Several officials told the newspaper that there are worries within the U.S. administration that Netanyahu might cancel the deal. Washington’s current strategy is to prevent the Israeli prime minister—through U.S. special envoy Steven Whitlock, Vice President J.D. Vance, and Jared Kushner, Trump’s son-in-law—from carrying out “a large-scale attack on the Palestinian militant group Hamas.”

The newspaper notes that negotiators from several Arab countries have gathered in Cairo to help mediate the deal. Additionally, U.S. authorities are cooperating with Turkey to form a team to locate the bodies of hostages killed in the enclave.

On October 9, Trump announced that representatives from Israel and Hamas had reached an agreement on the first phase of the plan, which includes the release of all hostages held in Gaza and the withdrawal of Israeli troops to agreed positions. On the night of October 10, Netanyahu’s office confirmed that the government had approved the agreement to release all hostages. The truce portion of the agreement went into effect on October 10.

On Sunday, the Israeli army reported that Palestinian militants had violated the truce in the Rafah area of southern Gaza, targeting Israeli soldiers. Netanyahu accused Hamas of breaking the ceasefire and instructed the military to “take measures” against the militants. Subsequently, the army carried out a series of strikes across the enclave, hitting dozens of targets. Later, Israeli authorities clarified that two soldiers were killed and another seriously injured during the incident in Rafah. Hamas representatives denied involvement in the Rafah events.
