AS IT HAPPENED: Peace talks in Pakistan end with no deal; Netanyahu vows 'Israel will continue to fight'; US claims warships entering Strait of Hormuz

That concludes today's live blog on the war in the Middle East. US Vice President JD Vance said the US failed to secure any peace deal with Iran.

He said the US had been "quite flexible and quite accommodating".

Australians should not expect any significant reduction in fuel prices despite the government's deal with Singapore to keep refined oil flowing into the country.

And the federal government is facing criticism after spending $20 million on a fuel-saving campaign to encourage Australians to reduce driving and conserve petrol as the war continues to wreak havoc on prices and supply.

The East-West pipeline, used to send oil to the Red Sea for transport, was repaired after an attack, the Saudi Energy Ministry said in a statement on Sunday, AP reports.

It said it has full capacity of about seven million barrels a day.

The pumping station was attacked on Thursday, affecting about 700,000 barrels of output through the pipeline, which has allowed Saudi Arabia to continue exporting a substantial portion of its oil.

Saudi Aramco operates the pipeline from the Aqaiq oil processing center near the Persian Gulf to the Yanbu port on the Red Sea, avoiding the Iranian chokepoint on the Strait of Hormuz and the Persian Gulf.

The ministry said the Manila oil field was also repaired, restoring a capacity of around 300,000 barrels a day.

It said work was still underway at another field, Kurais, to restore a capacity of another 300,000 barrels a day.

Iran's state-run TV said the delegation left Pakistan's capital after talks with the US failed to reach a deal, says Associated Press.

While the talks were being conducted in Islamabad, the US military said two destroyers transited the Iran-gripped Strait of Hormuz ahead of mine-clearing work, a first since the war began.

Iran's state media, however, said the joint military command denied that.

"We're sweeping the strait. Whether we make a deal or not makes no difference to me," Trump told journalists as talks continued and the time approached 2am in Islamabad. He called negotiations "very deep."

Iranian state TV noted what it called "serious" differences.

Trump briefly spoke to reporters earlier on Saturday while departing for Miami, CNN reports.

When asked how negotiations were going in Pakistan, Trump said it "makes no difference to me" whether a deal is reached between the US and Iran.

A spokesperson for Iran's foreign ministry says disagreement on "two, or three key issues" prevented a deal with the United States in Islamabad, CNN says.

Esmaeil Baqaei told state broadcaster IRIB on Sunday the two sides did reach agreement on some issues but said there was a "gap in viewpoints" on other matters.

Pakistan's Foreign Minister Ishaq Dar called on Iran and the United States to keep their commitment to maintain a ceasefire, after both countries ended historic face-to-face talks without an agreement.

"It is imperative that the parties continue to uphold their commitment to ceasefire," Dar said.

He added that Pakistan will continue to play is mediating role and will try to keep facilitating the dialogue between Iran and the US in coming days.

The federal government is facing criticism after spending $20 million on a fuel-saving campaign to encourage Australians to reduce driving and conserve petrol as the war in the Middle East continues to wreak havoc on prices and supply.

In a campaign blitz titled "Every little bit helps", the government will urge the public to reconsider driving habits, take public transport and offer tips for better fuel efficiency.

Vice President JD Vance boarded his government plane at 7.08am local time in Islamabad, planning to depart Pakistan after he said that Iran declined to back down on developing a nuclear weapon.

That's according to a reporter traveling with Vance.

The war with Iran started at the end of February and the extensive talks ended after 21 hours.

The US and Iran agreed to a two-week ceasefire on April 7 for negotiations.

Vance spoke for about three minutes and took three questions.

Australians should not expect any significant reduction in fuel prices after the government struck a deal with Singapore to keep refined oil flowing into the country.

Singapore has assured Prime Minister Anthony Albanese that it will do everything in its power to ensure more than half of the country's fuel imports continue arriving in Australia.

But will this have any material impact on the still sky-high petrol and diesel prices?
