Trump on Sunday said that the U.S. will guide ships out of Strait of Hormuz.
President Donald Trump announced "major combat operations" against Iran on Feb. 28, with massive joint U.S.-Israeli strikes targeting military, government and infrastructure sites.
Following the announcement of a two-week ceasefire, initial U.S.-Iran talks in Pakistan in April failed to reach a peace deal.
Trump later announced the open-ended extension of the ceasefire and the continuation of a U.S. blockade until negotiations are concluded "one way or the other."
The United Arab Emirates' Foreign Ministry said on Monday that a tanker affiliated with the state-run Abu Dhabi National Oil Company was targeted by two drones while transiting the Strait of Hormuz in what it called an "Iranian terrorist attack."
U.S. Central Command on Monday denied a report from Iran's semi-official Fars News Agency claiming that an American warship was hit by two missiles while trying to transit the Strait of Hormuz.
"No U.S. Navy ships have been struck. U.S. forces are supporting Project Freedom and enforcing the naval blockade on Iranian ports," CENTCOM said in a post to X.

Iranian Foreign Ministry spokesperson Esmail Baghaei said during a Monday press conference that Tehran received a U.S. counter-proposal to end the war via mediators in Pakistan.
"The U.S. message was received through Pakistan and I will not discuss the details of the issues raised at this time, because these issues are still under review," Baghaei said.
"The issues raised about enrichment or nuclear materials are purely speculative and, at this stage, we are not talking about anything other than stopping the war completely," Baghaei said, adding, "The direction we will take in the future will be determined in the future."

Maj. Gen. Ali Abdollahi, the commander of Iran's Khatam al-Anbiya Central Headquarters, said in a statement carried by state media on Monday that "any foreign armed force, especially the invading U.S. army, if they intend to approach and enter the Strait of Hormuz, will be subjected to attack."
"We will maintain the security of the Strait of Hormuz with all our might and manage it powerfully," Abdollahi said. The commander said that "all commercial ships and tankers" should "refrain from any action to transit without coordination with the armed forces stationed in the Strait of Hormuz so that their security is not endangered."
The warning came after U.S. Central Command said it would on Monday begin the "Project Freedom" operation "to restore freedom of navigation for commercial shipping through the Strait of Hormuz." President Donald Trump announced the mission on Sunday.
