US has extended a limited waiver of the Jones Act for another 90 days to support domestic fuel supplies amid disruptions caused by the Iran war, according to a White House spokesperson.

The extension allows foreign-flagged vessels to transport certain energy resources between US ports, easing restrictions imposed under the century-old shipping law.

Unlike the previous blanket waiver, the new extension will be applied on a voyage-by-voyage basis.

The Pentagon will consult the US Maritime Administration to determine whether individual shipments qualify, according to White House spokeswoman Taylor Rogers.

The Israeli army has carried out explosions, artillery shelling, a ground incursion and house burnings in southern Lebanon on Monday in continued violations of the ceasefire, according to Lebanon's state news agency.

“I urged Iran to finally engage constructively in negotiations with regional neighbours & USA in order to bring the conflict to an end,” he said.

He also called for the unconditional reopening of the Strait of Hormuz, a key maritime route for global energy supplies.

“The Strait of Hormuz needs to be opened unconditionally, ensuring free and safe navigation for all,” he added.

US President Donald Trump’s administration has extended a limited waiver of the Jones Act for another 90 days on Monday to support domestic fuel supplies amid disruptions caused by the Iran war, according to a White House spokesperson.

US Treasuries have declined, in line with weakness across European bond markets, as investors braced for key inflation readings this week that could point to persistent price pressures, while keeping a close eye on continued geopolitical tensions in the Middle East as oil prices rose.

The move reversed part of Friday's rally, which followed weaker-than-expected US nonfarm payrolls data, as traders re-established short positions and pared long exposure.

Oil prices jumped about five percent as the United States and Iran remained far apart on terms to reopen the vital Strait of Hormuz.

The centre said Yemeni military drones targeted Houthi fighters on the Alam front in the Sixth Military Region, as well as the rear area of a Houthi camp on the same front.

Yemeni forces also targeted Houthi fighters in the Al-Zour-Rawdat Jaham area, as well as their air defence systems and a mortar position in the Al-Radha Mountains, it said.

Other drone strikes targeted Houthi equipment in the Al-Kasara sector and Houthi fighters on the Al-Akad front, the centre said.

Yemen's Presidential Leadership Council says the government has exercised restraint in pursuit of peace and will no longer tolerate Houthi attacks without consequences.

US Democratic Senator Chris Murphy has said that President Donald Trump has “lost this war” with Iran, arguing that continued fighting is weakening the US while strengthening Tehran.

“America is weaker. Iran is stronger,” Murphy told NBC, saying he would support even a “bad deal” to end the war and reopen the Strait of Hormuz.

He said the cost of reopening the strategic waterway was rising as negotiations remained stalled.

The US Central Command (CENTCOM) has said that American forces redirected 55 commercial vessels, disabled two and boarded two others as part of strict enforcement of a US blockade against Iran.

CENTCOM said in a post on the US social media platform X that US sailors were standing watch aboard the USS Ross (DDG 71), one of more than 20 US warships deployed to the Middle East in support of military missions, including enforcement of the blockade.

The command did not provide additional details about the vessels or the circumstances surrounding the actions in its post.

Iran will not give up control of the Strait of Hormuz under any circumstances, the head of the country’s Expediency Council has said.

Ayatollah Sadegh Amoli Larijani, whose council is tasked with resolving disputes between Iran’s top legislative institutions, said sovereignty over the strategic waterway belongs to Iran.

“We will not retreat at any cost, and the Strait of Hormuz will not return to its previous conditions,” he stated.

The US President says Washington is “only semi-negotiating” with Tehran while closely monitoring Iran’s deteriorating economy.

The former commander-in-chief of Iran's Revolutionary Guard, Mohsen Rezaei, has been named head of the country's highest national security body, the Iranian presidency announced.

"In light of the resignation of Mohammad Bagher Zolghadr from his position as secretary of the Supreme National Security Council and his appointment to new functions, President Masoud Pezeshkian has named Mohsen Rezaei as the head of this body," presidency spokesperson Mehdi Tabatabaei said on X.

Earlier, Iran’s Supreme Leader Mojtaba Khamenei appointed Rezaei as his representative to the Supreme National Security Council.

“Considering your valuable experience, I am hereby appointing you, who were one of the first commanders in the triumphant 8-year Sacred Defence, to be my representative in the Supreme National Security Council,” Khamenei said on X.

Iran uses the term “Sacred Defence” to refer to the 1980–1988 Iran-Iraq War.

Rezaee commanded the Revolutionary Guard from 1981 to 1997 and is a member of Iran’s Expediency Discernment Council, an assembly that resolves differences between parliament and the Guardian Council, a 12-member body that vets candidates for office as well as legislation.

​​​​​​​Khamenei had appointed Rezaei as his military adviser in March.

After months of US military strikes on Iran, sanctions and a blockade, President Donald Trump has said that his administration is watching economic pressure mount on Iran, according to an interview with Axios.

"We are low-keying it," Trump was quoted as saying during a brief phone call.

"We are only semi-negotiating with them. We are just watching Iran with its huge inflation and the fact they have no money."

Foreign Minister Abbas Araghchi says Tehran will not return to negotiations until Washington fulfils its commitments, as a separate Iran-Oman agreement on the Strait of Hormuz nears completion.
