Supporters gathered in Tel Aviv’s “Hostage Square” could be seen holding up a large banner thanking President Donald Trump this morning.

"Our hope rests with you," the banner it said along with message of gratitude.

Many in Israel have credited Trump and Steve Witkoff, his special envoy to the Middle East for their help in getting the ceasefire and hostage release deal over the line.

As they prepare to reunite, Israeli solider Agam Berger’s family praised their “strong, faithful, and brave” daughter in a statement this morning.

“Thank God we have reached this moment, and our hero Agam has returned to us after 482 days in enemy hands,” said the statement, released by the Hostage Families Forum advocacy group.

"Now Agam and our family can begin the healing process, but the recovery will not be complete until all the hostages return home," the statement added.

In video released by the Israeli military, Berger's loved ones could be seen celebrating as they watched video of her being freed.

Four vehicles from the International Committee of the Red Cross (ICRC) have arrived in Gaza's southern city Khan Younis.

The ICRC is acting as a neutral intermediary in the handover of Israeli hostages and Palestinian prisoners under the ceasefire agreement.

In the past a team of specialists who have been involved have helped to peacefully secure the transfers.

Hamas fighters arrived in dozens of military vehicles at the destroyed house of the militant group's former leader Yahya Sinwar in Gaza's southern city Khan Younis.

Dressed in military uniforms, most of them were wearing green and black bandanas to represent Hamas' military wing, the Al Qassam Brigades, and Islamic Jihad, footage taken at the scene showed. Thousands of watched from the sidelines.

Hamas spokesperson Abu Ataya said in a statement on Telegram that they were joined by fighters from the the Al-Quds Brigades, the military wing of Islamic Jihad and other militant groups.

Friends of Agam Berger said they were feeling "pure bliss" after receiving the news that she had crossed into Israeli territory following her release from Hamas captivity.

“I’m waiting to see the pictures of her hugging her parents because I love them,” Yoni Collins, a friend of Berger’s, told NBC News in Tel Aviv’s “Hostage Square.”

“We’ve been waiting so long for this,” said Collins, 29, holding up a sign of his friend.

He added that he still had friends whose loved ones were still in Hamas’ custody. “We’re waiting for them to come home and we won’t stop until they all do,” he said.

Some of the Palestinian families awaiting the release of their loved ones from Israeli custody as part of today's hostage exchange have been warned not to celebrate, an official overseeing their release told NBC News.

Speaking in Ramallah in the occupied West Bank, Khalil Falama said Israeli forces had visited the homes of some of the families and warned them against any celebrations.

Falama, 56, said Palestinian prisoners and detainees were expected to be released between around 11:30 and 1 p.m. local time (4:30 and 6 a.m. ET).

Whether they were arrested for a social media post or killing Israelis, Palestinian prisoners are often seen by their community as having played their part in the resistance against the Israeli military occupation. Terrorists to Israelis, freedom fighters to Palestinians.

Those held in under a controversial practice known as “administrative detention,” which Israel uses to hold people without trial or other usual legal proceedings, based on alleged secret evidence it does not share with detainees, their families or legal representatives, are seen as hostages of the Israeli prison system.

The practice has been criticized by rights groups like Amnesty International and Human Rights Watch who say it has been used to hold Palestinians without charge and due process.

But Israel has defended the practice as a necessary security measure.

Agam Berger has crossed into Israeli territory, according to joint a statement from the IDF and the Israeli Security Agency.

It said Berger was “on her way to an initial reception point in southern Israel where she will be reunited with her parents.”

Scores of people have gathered in Tel Aviv’s “Hostage Square” to celebrate the release of Israeli soldier Agam Berger and await news of the seven other hostages set to be freed by Hamas today.

Many could be seen holding up signs of the hostages who are slated for release, including Arbel Yehoud, 29, Gadi Moses, 80, and five Thai hostages who have not been named. Others held up signs bearing the names and faces of hostages who remain held in Hamas' captivity.

“Mixed in with the joy of the release of Agam Berger is the anguish of the families of the hostages who are still in Gaza, both alive and dead,” the Hostages Families Forum, a group representing the families of those held captive in the enclave, said in a statement this morning following Berger’s release.
