WASHINGTON — Former British Prime Minister Tony Blair has joined a White House meeting with US President Donald Trump to discuss plans for post-war Gaza..

Middle East envoy Steve Witkoff has said the US is putting together a "very comprehensive" plan on "the next day" after the war. However, little else has been disclosed about the meeting.

Blair served as Middle East envoy for a few years after leaving office in 2007 — focusing on bringing economic development to Palestinian areas and creating conditions for a two-state solution.

However, when Israel's Foreign Minister Gideon Saar was asked by reporters what the plan was for a Palestinian state, he said there would not be any.

The White House meeting came after the Israeli military warned Palestinians that the evacuation of Gaza City was "inevitable", as its forces prepare to conquer it.

Israeli tanks pushed into a new area of the city overnight, destroying houses and forcing more residents to flee, witnesses said.

Thousands of people have already moved because of recent Israeli advances — mostly to other parts of the city, where about a million Palestinians still live.

In early August, Israel announced plans to occupy the whole Gaza Strip — including Gaza City, which it described as Hamas's last stronghold.

The UN and non-governmental organisations have warned that an Israeli offensive in Gaza City — where a famine was declared last week — would have a "horrific humanitarian impact".

In a statement on Wednesday, all the members of UN Security Council, with the exception of the US, called the famine in Gaza a "man-made crisis" and expressed "profound alarm and distress" at the latest report from the Integrated Food Security Phase Classification (IPC).

The statement called for Israel to immediately "and unconditionally" lift restrictions on humanitarian aid, reiterating that the use of starvation "as a weapon of war" is prohibited by international law.

In an interview with Fox News on Tuesday, Steve Witkoff said he believed the war in Gaza could be ended in the next four months.

"We're going to settle this one way or another, certainly before the end of this year," he stated.

Asked about a plan for governing post-war Gaza, he said: "It's a very comprehensive plan we're putting together on the next day that I think many people are going to... see how robust it is and how it's how well meaning it is, and it reflects President Trump's humanitarian motives here."

The White House said: "President Trump has been clear that he wants the war to end, and he wants peace and prosperity for everyone in the region."

No details have been released about the post-war Gaza proposals under discussion. However, in February Trump suggested that Gazans could be permanently relocated to neighbouring countries, with the US taking over the territory to transform it into "the Riviera of the Middle East".

The Axios website reported that Trump's son-in-law and former senior adviser, Jared Kushner, was also at the meeting.

On the ground in Gaza City, tanks entered the northern Ibad al-Rahman district on Tuesday night, destroying several homes, witnesses told Reuters news agency.

"All of a sudden, we heard that the tanks pushed into Ibad al-Rahman, the sounds of explosions became louder and louder, and we saw people escaping towards our area," Saad Abed said in a message from his home in Jala Street, about 1km (0.6 miles) away.

On Wednesday, the tanks reportedly retreated to Jabalia, an area further north where they have been operating.

Bombardment also continued in Gaza City's Shejaiya, Zeitoun and Sabra districts.

The Israeli military said in a statement on Wednesday that its troops had engaged in combat in the Jabalia area and on the outskirts of Gaza City, adding that they had eliminated a "terrorist cell" and located a weapons storage facility.

In a post on X on Wednesday, the military's Arabic spokesman Avichay Adraee said that "evacuating Gaza City is inevitable" and told residents to relocate to southern Gaza.

He said there was "empty space" and that each family making the move would "receive the most generous humanitarian aid".

Last week, the UN and non-governmental organisations warned that forcing hundreds of thousands of people to evacuate Gaza City and head south was "a recipe for further disaster and could amount to forcible transfer".

They also said the areas of the south where displaced residents were expected to move were "overcrowded and ill-equipped to sustain human survival at scale".

Prime Minister Benjamin Netanyahu said Israel would conquer the entire Gaza Strip after indirect talks with Hamas on a ceasefire and hostage release deal broke down last month.

But he is facing both international and domestic pressure to not proceed with the offensive.

On Tuesday evening, tens of thousands of protesters gathered in Tel Aviv demanding a ceasefire deal to bring home the remaining Israeli hostages held by Hamas. Only 20 of the 50 hostages are believed to be alive.

Israel has not accepted the latest proposal from regional mediators for a 60-day truce and the return of around half of the hostages, saying it will now only agree to a comprehensive deal to bring back all the hostages and end the war on its terms.

The Israeli military launched a campaign in Gaza in response to the Hamas-led attack on southern Israel on 7 October 2023, in which about 1,200 people were killed and 251 others were taken hostage.

Almost 62,900 people have been killed in Gaza since then, according to the Hamas-run health ministry.

Most of Gaza's population has also been repeatedly displaced; more than 90% of homes are estimated to be damaged or destroyed; and the healthcare, water, sanitation and hygiene systems have collapsed; and UN-backed global food security experts have confirmed that there is famine in the Gaza City area. — BBC
