TEL AVIV — Israeli negotiators have reached agreement with the Hamas terror group for a hostages-for-cease-fire deal that will also reportedly see the release of thousands of Palestinian security prisoners, many with blood on their hands, and an Israeli military withdrawal from key areas of the Gaza Strip.

“I am trying to breathe,” Efrat Machikawa, the niece of Israeli captive Gadi Moses, told Fox News Digital in response to the development.

“We will not know for sure that it is really happening until we will get the phone call to come see Gadi at the hospital. Although I am optimistic by nature, I am trying to control myself because we were very close to so many deals since the last one when my aunt Margalit was released,” Machikawa said.

The breakthrough in long-stalled negotiations came after the U.S. Middle East envoy, Steve Witkoff, met with Israeli Prime Minister Benjamin Netanyahu over the weekend in Jerusalem. The two held a “tense” meeting, according to local media, with Witkoff having demanded significant concessions.

Trump warned on Monday that the failure to reach an agreement would have consequences.

“If they don’t get it done, there’s going to be a lot of trouble out there like they have never seen before,” he stated.

During Hamas’s terror invasion 467 days ago, the Bibas family, including mother Shiri, husband Yarden and their children, Ariel, 4, and 9-month-old baby Kfir, were taken by Hamas terrorists from Kibbutz Nir Oz.

“We hope they’ll come back alive and we can get them treated, to do the best for them to readjust. But we don’t know in what situation they will return. We are very afraid,” Jimmy Miller, Shiri Bibas’s cousin, told Fox News Digital.

“I hope for the best, but I don’t want to be disappointed if something bad happens. I try not to think about it too much before it really happens. We thought it would happen before. Saturday is Kfir’s [second] birthday. Maybe he can celebrate it with us even a few days later,” he added.

The Hostages and Missing Families Forum Headquarters issued a statement, “We, the families of 98 hostages, welcome with overwhelming joy and relief the agreement to bring our loved ones home. We wish to express our profound gratitude to President-elect Trump, President Biden, both administrations, and the international mediators for making this possible. Since November 2023, we have been anxiously awaiting this moment, and now, after over 460 days of our family members being held in Hamas tunnels, we are closer than ever to reuniting with our loved ones.

“This is a significant step forward that brings us closer to seeing all hostages return – the living to rehabilitation, and the deceased for proper burial,” the statement continues. “However, deep anxiety and concerns accompany us regarding the possibility that the agreement might not be fully implemented, leaving hostages behind. We urgently call for swift arrangements to ensure all phases of the deal are carried out.”

“We will not rest until we see the last hostage back home.”
