President Donald Trump posted on Truth Social on Wednesday that Israel and Hamas had agreed to the “first phase” of the peace plan to end the war in Gaza and both parties acknowledged that an agreement had been reached.

"I am very proud to announce that Israel and Hamas have both signed off on the first Phase of our Peace Plan. This means that ALL of the Hostages will be released very soon, and Israel will withdraw their Troops to an agreed upon line as the first steps toward a Strong, Durable, and Everlasting Peace," Trump wrote. "All Parties will be treated fairly! This is a GREAT Day for the Arab and Muslim World, Israel, all surrounding Nations, and the United States of America, and we thank the mediators from Qatar, Egypt, and Turkey, who worked with us to make this Historic and Unprecedented Event happen. BLESSED ARE THE PEACEMAKERS!"

Hamas also confirmed reaching an agreement on the peace plan in a statement on Wednesday.

"After responsible and serious negotiations between the movement and the Palestinian resistance factions regarding President Trump’s proposal in Sharm el-Sheikh, with the goal of reaching an end to the war of extermination against our Palestinian people and the occupation’s withdrawal from the Gaza Strip, the Islamic Resistance Movement (Hamas) announces the conclusion of an agreement stipulating an end to the war on Gaza, the occupation’s withdrawal from it, the entry of aid, and a prisoner exchange," the statement said.

Hamas asked "President Trump, the guarantor states of the agreement, and various Arab, Islamic, and international parties to compel the [Israeli] government to fully implement the agreement’s requirements" in the statement.

Israeli Prime minister Benjamin Netanyahu also acknowledged that an agreement had been reached in a post on X on Wednesday.

"A great day for Israel. Tomorrow I will convene the government to approve the agreement and bring all our dear hostages home," he wrote.

Netanyahu added, "I thank from the depths of my heart President Trump and his team for their mobilization for this sacred mission of releasing our hostages."

U.N. Secretary-General António Guterres expressed support for the agreement in a statement on Wednesday.

“The United Nations will support the full implementation of the agreement and will scale up the delivery of sustained and principled humanitarian relief, and we will advance recovery and reconstruction efforts in Gaza,” the statement said.

Guterres added, "The stakes have never been higher."

Trump had said earlier that he may travel to the Middle East at the end of the week but did not specifically say he would be going to Egypt, where peace talks are being held.

"I may go there sometime toward the end of the week, maybe on Sunday, actually," Trump told reporters at the White House.

Secretary of State Marco Rubio passed a note to Trump at the White House gathering with reporters and walked over to speak to him.
