Thousands of displaced Palestinians trekked over the wastelands of Gaza to return to the ruins of their abandoned homes on Friday, after a ceasefire took effect and Israeli troops began pulling back under the first phase of an agreement to end the war.

A huge column of people filed on foot north along the coastal road overlooking sandy beaches towards Gaza City, the enclave’s biggest urban area, which had been under attack just days ago in one of Israel’s biggest offensives of the war.

“Thank God my house is still standing,” Ismail Zayda, 40, said in the Sheikh Radwan district of Gaza City.

“But the place is destroyed, my neighbours’ houses are destroyed, entire districts have gone.”

In the south, people picked their way through the dusty moonscape that was once Gaza’s second-largest city, Khan Younis, which Israeli forces had razed this year. Most walked in silence.

A middle-aged man, Ahmed Al Brim, was pushing a bicycle with bundles of scrap timber tied to the front and back: his family would need the firewood to cook.

It was all they had been able to recover from the ruins of their home.

“We went to our area. It was exterminated. We don’t know where we will go after that,” he said. “We couldn’t get the furniture, or clothes, or anything, not even winter clothes. Nothing is left.”

Palestinian health authorities said medical teams were able to recover 100 bodies from areas across the Gaza Strip after the army pulled back.

Even as Gazans headed home, questions loomed about whether the ceasefire and hostage-prisoner exchange deal between Israel and Hamas, the biggest step yet toward ending two years of war, would lead to a lasting peace under US President Donald Trump’s 20-point plan to end the war.

Speaking to reporters at the White House, Trump expressed confidence the ceasefire would hold, saying: “They’re all tired of the fighting.”

He said he believed there was a “consensus” on the next steps, but acknowledged some details would still have to be worked out.

Netanyahu warns Hamas

The Israeli military said the ceasefire agreement had been activated at noon local time.

The first phase of Trump’s plan to halt the conflict between Israel and the Hamas group gives Israeli troops 24 hours to pull from positions in urban areas, although they will still hold more than half of Gaza.

Israeli police said they were preparing for Trump’s visit on Monday, which officials said would include a speech to the Knesset, Israel’s parliament, the first by a US president since George W. Bush in 2008.

Trump said he would head to the Middle East in the coming days and planned to address Israel’s parliament in Jerusalem.

He said he would also travel to Egypt and that other world leaders were expected to be present.

Axios reported earlier that Trump plans to convene an international summit on Gaza while in Egypt.

The next phase of Trump’s plan calls for an international body – the “Board of Peace” – to play a role in Gaza’s post-war administration.

The plan calls for Trump to lead it and includes former British Prime Minister Tony Blair.

But in a potential challenge to this element of the plan, Hamas issued a statement late on Friday rejecting what it called any “foreign guardianship,” adding that governance of Gaza was purely an internal Palestinian matter.

In a televised address, radical Israeli leader Benjamin Netanyahu said Israeli forces were staying in Gaza to ensure Hamas was disarmed: “If this is achieved the easy way, then that will be good, and if not, then it will be achieved the hard way.”

As the day wore on and it became clear that troops were no longer blocking the roads into cities, an initial trickle turned into a flood of Palestinians returning from makeshift tented camps to the homes they had left behind.

Mahdi Saqla, 40, said his family had decided to set off north towards Gaza City as soon as they heard the news of the ceasefire.

“Of course there are no homes – they’ve been destroyed,” he said.

“But we are happy just to return to where our homes were, even over the rubble. That too is a great joy. For two years, we’ve been suffering, displaced from place to place.”

Israel’s government ratified the ceasefire with Hamas in the early hours of Friday.

Once Israeli troops have pulled back, Hamas has 72 hours to release the 20 living Israeli hostages it is still holding.

Trump said the hostages are due to “come back” on Monday.

Israel will free 250 Palestinians serving long terms in its prisons and 1,700 detainees captured during the war.

Hundreds of trucks per day are expected to surge into Gaza carrying food and medical aid.

Israeli military spokesperson Brigadier General Effie Defrin urged residents of Gaza to avoid entering areas under Israeli military control: “Keep to the agreement and ensure your safety,” he said on Friday.

Hamas leader receives guarantees

Israelis and Palestinians alike rejoiced after the deal was announced, to end two years of war in which over 67,000 Palestinians have been killed, and to return the last hostages seized by Hamas in the deadly attack that provoked it.

The exiled Gaza chief of Hamas, Khalil Al Hayya, said he had received guarantees from the United States and other mediators that the war was over.

Hamas has indicated that recovering the bodies of the dead may take longer than releasing those who are alive.

Hurdles remain

The accord, if fully implemented, would bring the two sides closer than any previous effort to halt the war.

Much could still go wrong. Further steps in Trump’s 20-point plan have yet to be agreed upon.

Those include how the demolished Gaza Strip is to be ruled when fighting ends, and the ultimate fate of Hamas, which has rejected Israel’s demands that it disarm.

The Hamas-run interior ministry said it would deploy security forces in areas where the Israeli army withdrew. It was not clear whether armed militants would return to the streets in significant numbers, a move Israel would see as a provocation.
