It will be paused to see if an agreement can be reached with Iran, Trump said.
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."
Iran's Islamic Revolutionary Guard Corps issued a new warning to all vessels intending to transit in the strait, saying "the only safe route to pass through the Strait of Hormuz is the corridor previously announced by Iran," in a statement Tuesday.
"The diversion of vessels to other routes is unsafe and will face a decisive response from the IRGC Navy," the IRGC said.
President Donald Trump suggested that Iran hasn’t yet violated the ceasefire despite firing shots in the Strait of Hormuz, saying “I’ll let you know” when it is breached.
"They didn't shoot the ships that were guarded by us," Trump said during an Oval Office event on Tuesday.
"The blockade has been amazing. It's like a piece of steel. Nobody is going to challenge a blockade," Trump said.

Air defenses in the United Arab Emirates are dealing with projectiles launched from Iran, the Ministry of Defense said in a post on X Tuesday. It is unclear how many projectiles are involved.
"The Ministry of Defense confirms that the sounds heard in scattered areas of the country are the result of the UAE's air defense systems intercepting ballistic missiles, cruise missiles, and drones," the ministry said.
This comes after the UAE's Ministry of Defense said 15 missiles and four drones launched from Iran were engaged on Monday.
Defense Secretary Pete Hegseth told reporters that Iran does not control the Strait of Hormuz.
"They said they control the strait. They do not," Hegseth said.
"Iran has an ability to make that deal, but what we're demonstrating with Project Freedom is they don't control the strait. We know Iran is embarrassed by the fact that our blockade is holding, and we can run ships through, and we're going to help the world run ships through," Hegseth said Tuesday.
