The United States and Iran said on Friday that the Strait of Hormuz is now fully open to commercial vessels after a 10-day truce in Lebanon appeared to hold, but the US' military blockade of Iran remains in effect.

"The Strait of Hormuz is completely open and ready for business and full passage, but the naval blockade will remain in full force and effect as it pertains to Iran, only, until such time as our transaction with Iran is 100 percent complete," US President Donald Trump wrote on Truth Social in all caps.

Minutes earlier, Iranian Foreign Minister Abbas Araghchi posted on X that the passage for all commercial vessels through the strait "is declared completely open" in line with the ceasefire in Lebanon. He said it would stay open for the remaining period of the ceasefire.

Meanwhile in Lebanon, celebratory gunfire echoed across Beirut's southern suburbs, Hezbollah's stronghold, while displaced residents began heading south to return to their homes.

"There's destruction and it's unlivable. We're taking our things and leaving again," Fadel Badreddine, who came with his young son and wife, was quoted by Reuters as saying. "May God grant us relief and end this whole thing permanently."

Yet the truce remained highly fragile. Israel's military stated it had struck more than 380 Hezbollah targets in southern Lebanon and remained on high alert to resume operations. Israeli Prime Minister Benjamin Netanyahu ruled out troop withdrawals, emphasizing Hezbollah's disarmament as a precondition for any "historic peace agreement" with Lebanon.

Hezbollah lawmaker Ibrahim al-Moussawi said the group would "respect" the truce if Israel halts its attacks. He thanked Iran for pressuring on Lebanon's behalf, adding that "the ceasefire would not have been possible without Iran, which views this truce as equivalent to closing the Strait of Hormuz".

Iran has welcomed the ceasefire, describing it as part of an understanding reached with the US under Pakistani mediation that would pave the way for a broader pact to de-escalate the regional conflict, Iranian media reported, citing a Foreign Ministry statement.

Several regional states, including Saudi Arabia and Oman, have welcomed the truce. Riyadh reiterated its support for Lebanon's statehood and sovereignty, while Muscat called on all parties to refrain from any truce violations.

But Israel still lacks a political road map for lasting peace with Lebanon, as it has failed to disarm Hezbollah, said political commentator Abed Abou Shhadeh based in Jaffa, Israel.

"History over the past 40 years has proven this is not something Israel can achieve," he said.

"The military recently acknowledged that fully disarming Hezbollah would require occupying all of Lebanon — a mission it lacks the troop strength to carry out."

The Lebanon conflict, which erupted on March 2, has killed more than 2,000 people to date.

Trump said he had held "excellent conversations" with Netanyahu and Lebanese President Joseph Aoun and planned to invite them both to the White House for "meaningful talks". He later added that if a US-Iran deal is signed in Islamabad, he might travel there for the signing.

Abas Aslani, a senior fellow at the Center for Middle East Strategic Studies in Tehran, told Al Jazeera that Trump is seeking an exit ramp from the Iran war before it brings greater repercussions for the US and the global energy market.

"But it wouldn't secure any strategic outcome for the US," Aslani said. "There are some gaps that need to be bridged, but those differences remain."

In recent weeks, Trump has repeatedly claimed that the Iran war will end soon.

Experts said there is little credible evidence to back Trump's claim. Meanwhile, US Defense Secretary Pete Hegseth warned on Thursday that if Iran rejects a deal, the US military will target Iran's "infrastructure, power grid and energy sector".

Clay Ramsay, a researcher at the Center for International and Security Studies at Maryland, said the US administration cannot negotiate a comprehensive settlement. "Trump has a political incentive to claim peace on his terms is imminent. That does not make it a reality," he told Xinhua.
