U.S. President Donald Trump is set to host Israeli Prime Minister Benjamin Netanyahu for talks Tuesday at the White House with Israel’s ceasefire with Hamas militants in the Gaza Strip at the top of the agenda. The talks come at a key phase in the ceasefire. Israel and Hamas have less than four weeks to agree on the terms of the second phase, which would include the release of all remaining hostages held in Gaza, a permanent halt in fighting and Israel’s withdrawal from the territory. “I have no guarantees that the peace is going to hold,” Trump told reporters Monday. Ahead of the White House visit, Netanyahu met Monday with U.S. Middle East envoy Steve Witkoff, who was part of the push to secure the ceasefire deal. Netanyahu’s office said in a statement that the meeting was “positive and friendly,” and that he would meet with his Security Cabinet upon returning from the U.S. in order to “discus Israel’s overall positions regarding the second stage of the deal.” Witkoff is expected to hold talks with Qatari and Egyptian officials as the three countries continue in their role of mediating the halt in fighting. In addition to the ceasefire, Netanyahu said he and Trump would discuss countering Iranian aggression and expanding diplomatic relations with Arab countries. Trump brokered normalization agreements between Israel and four Arab countries in his first term. He now is seeking a wider agreement in which Israel would forge ties with Saudi Arabia. But Saudi Arabia has said it would only agree to such a deal if the war in Gaza ends and there is a credible pathway to a Palestinian state in Gaza, the West Bank and east Jerusalem, territories Israel captured in the 1967 Middle East war. The U.S. supports Palestinian statehood, but Netanyahu’s government is opposed. Hamas, a U.S.-designated terror group, has released 18 hostages so far, while Israel has freed hundreds of Palestinian prisoners. The war in Gaza began with the Oct. 7, 2023, attack in which Hamas militants killed 1,200 people and took about 250 people hostage. Israel’s counteroffensive during 15 months of warfare has killed more than 47,500 Palestinians, more than half of them women and children. Israel’s military says the death toll includes 17,000 militants it has killed. Some material in this report came from The Associated Press, Agence France-Presse and Reuters.
