BREAKING: Trump signs Israel-Hamas peace plan in Egypt alongside world leaders Read more about the historic deal:

President Donald Trump and several world leaders signed a historic Gaza peace plan following a summit in Egypt. This comes just hours after all 20 living Israeli hostages returned home from Gaza.

The president called it a “tremendous day for the world” and a “tremendous day for the Middle East.”

“This took 3,000 years to get to this point. Can you believe it? And it’s going to hold up too. It’s going to hold up,” Trump said after signing.

Israeli authorities said Hamas transferred two coffins of deceased hostages to the Red Cross , with two more expected to be delivered. There are 28 deceased hostages in total whose remains are expected to be released as part of the ceasefire deal.

“Hamas is required to uphold the agreement and take the necessary steps to return all the deceased hostages,” the IDF and Israel Security Agency said in a joint statement.

The Hostages and Missing Families Forum said it was “shocked and dismayed” to learn that Hamas was refusing to release the remains of all deceased hostages.

Israel Defense Forces (IDF) Brig. Gen. Effie Defrin celebrated the return of the hostages as a “defining moment,” which he said “belongs to the people of Israel, and all who believe in humanity,” as well as the fallen soldiers.

“We will not rest until the mission is complete. We are prepared for the return of all the fallen hostages, and expect Hamas to abide by the terms of the agreement,” Defrin said in a statement.

Earlier on Monday, the Hostages and Missing Families Forum accused Hamas of releasing just four of the 28 deceased hostages’ remains, violating the agreement brokered by the Trump administration.

President Donald Trump offered new details about how the Israel-Hamas ceasefire agreement came together on Monday, saying the U.S. strikes on Iran’s nuclear program were critical.

Trump made the comments in an interview with Fox News’ Trey Yingst in Israel on Monday. Trump received a warm welcome from Israeli lawmakers in Jerusalem before traveling to Sharm El-Sheikh, Egypt for a peace summit.

Trump told Fox that he was impressed by the enthusiasm “shown all over the world” for the release of the 20 living hostages back to Israel.

“I think it really started when we took out the nuclear capability of Iran,” Trump told Yingst. “When you look at what they had, you couldn’t have made this deal with someone sitting over there with a nuclear weapon over your head.”

Yingst said Trump emphasized that the Gaza deal is only the beginning of what he hopes will become a wider movement toward peace across the Middle East.
