US President Donald Trump said the US Navy told him all mines have been cleared from the Strait of Hormuz in a Tuesday Truth Social post.
"All mines have been removed and/or detonated from within the International Waters of the Strait of Hormuz," the president wrote.
A US official confirmed to The Jerusalem Post that both inbound and outbound shipping lanes in the strait have been cleared of mines by US Central Command (CENTCOM).
The official noted that the opening of the routes will allow for an increase in maritime traffic to transit the waterway.
Trump added that "Iran has been notified that any ship or boat placing new mines will be immediately and systematically destroyed."
"There is a Zero Tolerance policy on mine placement in full force and effect," he said.
Oman, Iran negotiating joint Hormuz navigation framework
Later Tuesday, Iran and Oman issued a joint statement announcing a proposed framework to resume safe navigation through the Strait of Hormuz.
The Omani Foreign Minister, Badr bin Hamad bin Hamoud Al-Busaidi, and the Iranian Foreign Minister, Abbas Araghchi, negotiated the framework.
According to the statement, the proposal includes joint efforts to establish a temporary navigation corridor through the waterway and a project to clear the strait of mines, despite Trump’s assertion that all mines have already been removed.
The joint statement claimed that Oman and Iran will continue negotiating the framework to reach a permanent agreement on the issue and to establish mechanisms for exchanging navigation information, managing ship traffic, and providing security services to vessels.
Trump claims Space Force watching Strait of Hormuz, Iranian nuclear sites
Trump claimed that in addition to keeping an eye on the Strait of Hormuz, the US is also closely watching Iranian nuclear sites.
"Through Space Force, we are watching every square inch of the Strait, as we are also with Pickaxe Mountain and the three other already destroyed nuclear sites."
Pickaxe Mountain is located 220 km. (140 miles) south of Tehran and 2 km. (1.2 miles) from the Natanz nuclear complex.
The Natanz site, where two of Iran's uranium enrichment plants were located, was bombed in June 2025, including by US Air Force B-2 stealth bombers as part of Operation Midnight Hammer, as well as by operations Roaring Lion and Epic Fury earlier in 2026.
