US President Donald Trump has given Hamas a deadline to accept a US peace plan for Gaza or face “all hell”.

Trump wrote on his Truth Social platform on Friday that an agreement must be reached by 18:00 Washington time (22:00 GMT) on Sunday.

The plan proposes an immediate end to fighting and the release within 72 hours of 20 living Israeli hostages held by Hamas – as well as the remains of hostages thought to be dead – in exchange for hundreds of detained Gazans.

Arab and Turkish mediators are understood to be pressing Hamas for a positive response to the proposal, but a senior Hamas figure has said the armed group is likely to reject it.

“If this LAST CHANCE agreement is not reached, all HELL, like no one has ever seen before, will break out against Hamas. THERE WILL BE PEACE IN THE MIDDLE EAST ONE WAY OR THE OTHER,” Trump wrote in the Truth Social post.

The deadline announced on Friday comes after Trump said on Tuesday that he was giving Hamas “three to four days” to respond to the peace plan.

Mediators have made contact with the head of Hamas’s military wing in Gaza, who has indicated he does not agree to the new US ceasefire plan, the BBC understands.

It is thought that some of Hamas’s political leadership in Qatar are open to accepting it with adjustments – but have found their influence limited as they do not have control of the hostages held by the group.

Another stumbling block for some in Hamas is that the plan requires them to hand over all of the hostages over the first 72 hours of the ceasefire – giving away their only bargaining chip.

There are believed to be 48 hostages still being held in the Palestinian territory by the armed group, only 20 of whom are thought to be alive.

The 20-point plan, agreed by Trump and Israeli Prime Minister Benjamin Netanyahu and announced by both at the White House on Monday, also says Hamas will have no role in governing Gaza, and leaves the door open for an eventual Palestinian state.

However, Netanyahu later reinstated his longstanding opposition to a Palestinian state, saying in a video statement shortly after the announcement: “It’s not written in the agreement. We said we would strongly oppose a Palestinian state.”

The plan stipulates that once both sides agree to the proposal “full aid will be immediately sent into the Gaza Strip”.

It also outlines a plan for the future governance of Gaza, saying a “technocratic, apolitical Palestinian committee” will govern temporarily “with oversight and supervision by a new international transitional body, called the Board of Peace”, which it says will be headed by Trump.

European and Middle Eastern leaders have welcomed the proposal. The Palestinian Authority (PA), which governs parts of the Israeli-occupied West Bank, has called the US president’s efforts “sincere and determined”.

Pakistan initially voiced support for the plan, but the country’s foreign minister has since said the points announced were not in line with a draft from a group of Muslim-majority countries, BBC Urdu and Reuters reported.

Trump has said that if Hamas does not agree to the plan, Israel would have US backing to “finish the job of destroying the threat of Hamas”.

Netanyahu has also said Israel “will finish the job” if Hamas rejected the plan or did not follow through.

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.

At least 66,288 people have been killed in Israeli attacks in Gaza since then, according to the territory’s Hamas-run health ministry.

In the 24 hours before Friday midday, 63 people were killed by Israeli military operations, the health ministry said.

The push for the peace plan comes as Israel is carrying out an offensive in Gaza City, with Israel’s defence minister saying earlier this week that Israeli forces were “tightening the siege” around the city.

Israel has said the offensive aims to secure the release of the remaining hostages.

Hundreds of thousands of Gaza City residents have been forced to flee after the Israeli military ordered evacuations to a designated “humanitarian area” in the southern al-Mawasi area, but hundreds of thousands more are believed to have remained.

Israel’s defence minister has warned that those who stay during the offensive against Hamas would be “terrorists and supporters of terror”.

James Elder, spokesman for the UN children’s agency, Unicef, said on Friday that the idea of a safe zone in southern Gaza was “farcical”.

“Bombs are dropped from the sky with chilling predictability. Schools, which have been designated as temporary shelters, are regularly reduced to rubble,” he said.

The United States’s 20-point plan to end Israel’s war in Gaza is not the same as the draft proposed by a group of Arab and Muslim countries, Pakistan’s Foreign Minister Ishaq Dar has said.

“I made it clear that the 20 points that President (Donald) Trump made public are not ours. Changes were made to our draft. I have the record,” Dar said, speaking to politicians on Friday, according to remarks carried by Dawn news.

His comments come after the White House on Monday released a plan with fanfare that would include a ceasefire, the return of all captives, Hamas disarmament, and a new political architecture for post-war Gaza – one that would exclude the Palestinian group.

Its release came a few minutes before Trump and Israeli Prime Minister Benjamin Netanyahu stood next to each other at the White House to announce the plan. There, Trump told Hamas it had 72 hours to accept the proposal. On Tuesday, he gave the Palestinian group three to four days to agree to the plan.

Meanwhile, Hamas political bureau member Mohammad Nazzal told Al Jazeera on Thursday that the group was discussing Trump’s plan and would soon announce its position on the proposal. “We are not dealing [with the plan] under the logic that time is a sword pointed at our neck,” Nazzal said.

The published document was presented as a joint effort between Israel, the US and a number of Arab and Muslim countries. Last week, several leaders from the Arab and Muslim world discussed the plan at a meeting on the sidelines of the United Nations General Assembly in New York.

But while there are no official records of what was discussed at that mini-summit, Axios reported that the proposal announced by the American and Israeli leaders earlier this week contained “significant changes”, requested by Netanyahu, to the draft that had been agreed on by the Arab leaders and Trump.

The amendments were made during a six-hour meeting between Trump’s son-in-law, Jared Kushner, US Special Envoy Steve Witkoff and Netanyahu, the report said. The revised version ties Israel’s withdrawal to Hamas’s disarmament and allows Israel – after a withdrawal in stages – to remain within a buffer zone inside the enclave until there are no risks of any “terror threat”, it added.

A group of eight Arab and Muslim countries, including Pakistan, Qatar, Turkiye and Saudi Arabia, welcomed Trump’s announcement in a joint statement.

Qatar has said that it agrees with the aims of the plan, and seeks further discussions on its details.

“If we speak of the main objectives, there are objectives that it [the US plan] achieves, such as ending the war, and there are things that need clarification, which certainly need discussions and negotiations,” Qatar’s Prime Minister Sheikh Mohammed bin Abdulrahman bin Jassim Al Thani told Al Jazeera.

Egypt’s Foreign Minister Badr Abdelatty also said that more talks were needed. According to the US proposal, an international body chaired by Trump would have oversight, while a Palestinian technocratic committee would handle civilian governance until the Palestinian Authority reforms itself. To take care of security, according to the proposal, a stabilisation force would be deployed.

“There are a lot of holes that need to be filled; we need more discussions on how to implement it, especially on two important issues – governance and security arrangements,” Abdelatty said on Thursday.

Experts pointed out that there are sticking points. There are questions on whether Hamas will agree to disarm since it has repeatedly said it would not, as the main face of Palestinian armed resistance.

The current proposal also nods vaguely at how reforms may open a pathway to Palestinian statehood, which is not recognised as a right but as the “aspiration of the Palestinian people”.

The plan does not mention the forced displacement of Palestinians from Gaza – a significant shift from Trump’s earlier lambasted position when he suggested the relocation of the population outside the enclave to turn it into the “Riviera of the Middle East”, which was heavily criticised as ethnic cleansing.

It also ruled out the occupation of Gaza and the annexation of the occupied West Bank – actions that Netanya’s far-right coalition members are pushing for.

Should Hamas refuse the deal, Trump ominously told Netanyahu, “You will have our full backing to do what you have to do.”

Japan is facing a shortage of Asahi products, including beer and bottled tea, as the drinks giant grapples with the impact of a major cyber-attack that has affected its operations in the country.

Most of the Asahi Group’s factories in Japan have been at a standstill since Monday, after the attack hit its ordering and delivering systems.

Major Japanese retailers, including 7-Eleven and FamilyMart, have now warned customers to expect shortages of Asahi products.

In a statement on Friday, Asahi said it was “unable to provide a clear timeline for recovery” but had started “partial manual” processing of orders and shipments.

Asahi is the biggest brewer in Japan, but it also makes soft drinks and food products, as well as supplying own-brand goods to other retailers.

It owns Fullers in the UK and global brands including Peroni, Pilsner Urquell and Grolsch. However, Asahi has said that only its operations in Japan – which account for about half its sales – have been affected by the attack.

In its latest statement, Asahi said that as a result of containment measures following the attack, ordering and shipment systems in Japan had been affected and it was also unable to receive emails from external sources.

“Although system-based order and shipment processes remain suspended, ensuring product supply to customers has been set as our top priority and we have begun partial manual order processing and shipment,” it said.

Asahi also said it was preparing to reopen its call centre operations next week.

Atsushi Katsuki, Asahi president and group chief executive, apologised for the disruption.

“We are making every effort to restore the system as quickly as possible, while implementing alternative measures to ensure continued product supply to our customers,” he said.

In a statement on Thursday, FamilyMart – which is one of Japan’s largest convenience stores – said its Famimaru range of bottled teas, which are made by Asahi, were expected to be in short supply or out of stock.

“We sincerely apologise to our customers for any inconvenience caused,” said FamilyMart, adding that it was working with Asahi to resume the sale of the products.

7-Eleven, the Japanese-owned global convenience store chain, has halted shipments in the country of Asahi products, including its popular Super Dry beer.

A spokesperson for 7-Eleven said its shops have been advised to expect a shortage of Asahi products.

Lawson, another major Japanese retailer, also said it expected some Asahi products to be in short supply from Friday.

The retailer said it planned to stock up on alternative products to minimise the impact on customers.

Japanese supermarket chain Life Cooperation also warned that Asahi products may soon go out of stock.
