Hamas says it’s seeking firm guarantees from Trump and mediators that Israel won’t resume its military campaign in the Palestinian territory after the militant group releases all the remaining hostages.

All sides have expressed optimism for a deal to end the two-year war that has left tens of thousands of Palestinians dead and most of the Gaza Strip destroyed. But key parts of the peace plan still haven’t been agreed to, including a requirement that Hamas disarm, the timing and extent of an Israeli troop withdrawal from Gaza, and the creation of an international body to run the territory after Hamas steps down.

Trump’s Middle East envoy, Steve Witkoff, and his son-in-law, Jared Kushner, arrived Wednesday at Sharm el-Sheikh for the discussions, as did Qatar’s prime minister, Sheikh Mohammed bin Abdulrahman Al Thani, and Israeli Prime Minister Benjamin Netanyahu’s top adviser, Ron Dermer.
